WHY SHOULD I DIVE WITH A DIVE COMPUTER?

You just finished your Scuba Diver Course and your head is spinning with all the knowledge and skills you have learned. At the top of your list is purchasing what your instructor may have said was the most important piece of dive gear you could own – a dive computer. Your question is, “Why? What is so important about a personal dive computer (PDC) that I should have my own?”

So, getting down to the basics means that there are three things you absolutely need to know during your dive: Where are you now? How long have you been there? How much longer can you stay? This translates into depth, elapsed dive time (EDT), and no decompression limit (NDL). All dive computers answer these questions, but ease of use, readability and additional dive information vary greatly between models.

Depth is one of the first things we set a limit on. Diving within the agreed upon depth limit, whether it be with the Divemaster, your dive buddy, or a solo dive, is the first decision a diver makes prior to the dive. Not sticking to your planned depth can be dangerous. The easiest way to monitor your depth is with the constant depth display on your PDC. An audible alarm is an important feature to alert you to any unplanned depth changes during the dive, including ascents. Your PDC will have an ascent rate indicator that allows you to insure you are ascending no faster than 30′ per minute. You won’t just descend to the bottom and swim around just off the sand. Many wrecks, reefs and rigs stick up off the bottom allowing you to do a 60′ dive on a rig in 200′ of water. But there aren’t any stop signs, so contantly being aware of your depth is important.

No decompression limit is one of 2 primary limitations when planning and conducting a dive profile. Some computers have audible alarms for this feature as well. Not following a good dive plan with regard to our profile (depth and time) could result in decompression illness. Going too deep, coming up too fast, and staying too long, greatly increases your risk for DCS. NDL takes your depths and times during each dive or repetitive dives and calculates how much longer you can safely stay at your current depth based on everything you’ve done up to this point. Breaking these rules could cause the loading of too much nitrogen resulting in a mandatory decompression stop. As a new diver, you want to avoid a deco stop at all costs. Your PDC can tell you when to move to a shallower depth, will continuously recalculate your NDL for the new depth. Not only does this keep you safely within your nitrogen limit, but it will significantly extend your dive times over the square profile associated with dive tables because it credits you back for times spent at shallower depths. Every single dive you do is a mutli-level dive.

The 2nd primary limitation is air consumption. You must continually monitor NDL and air consumption during the dive to be back on the surface with a safety reserve of air (usually 500 psi) and within the NDL. Your pressure gauge will give you your current tank pressure, but doesn’t give you any air time or consumption information. An air-integrated PDC gives you a digital display of tank pressure and because it has this extra piece of important information, can calculate the current depth and the rate you have been consuming air. So, simply it will tell you how much longer your air will last. The PDC then compares your remaining NDL and remaining air and tells you how much longer you can stay based on which is the limiting factor.

The easiest and safest computers are air-integrated with user settable audible alarms. This style lets you set alarms for minimum tank pressure, maximum depth, minimum NDL, ascent rate and many other parameters. Then if you approach or exceed any of these it will start beeping to get your attention and tell you what you need to do.

Even if you are primarily a traveling diver and rent equipment, most divers prefer to have their own computer. This way you are familiar with it’s use and display and don’t have to spend your bottom time studying the display to decipher it. Most important to American divers is that your personal computer gives you information in imperial form. Most of the world is metric and I can promise many frustrating minutes underwater mentally converting meters to feet and bar to psi!

Every dive is full of distraction from the moment our head goes underwater. Most of these distractions are the reason we are there: colorful fish and corals, dolphins, turtles, underwater cameras, spearguns, weightlessness, seashells, shipwrecks, pirate treasure & mermaids. But these fun distractions are constantly drawing your attention away from the tasks of monitoring your air return point, air ascent point, depth, duration and direction. A dive computer is the most important tool to assist in conducting a safe, relaxed and enjoyable dive.Digital Camera

My type of “spring cleaning” is a mess of sheephead on the fish-cleaning table.  The water is warming quickly and the wind is calming, so more anglers and spearfisherman are starting to venture into the gulf.

Getting the boat out and scrubbing the winter coat of mildew is made easier by the anticipation of the coming season.  The talk of the shortest snapper season and stricter limits on other species doesn’t dampen the excitement of the first trip.  Some of us have been spearing fish all winter, when the seas would let us escape the dock.  For many, their first excursion in 2013 is this month.  Besides staring at a wall of red snapper and remaining alert for early cobia, we pass the time underwater stacking up sheephead.

 sheephead

This is a great fish to target this time of year because their numbers are plentiful.  They aren’t a spooky fish that will disappear after shooting 1 or 2, and usually allow for a close shot.  They are plentiful for only a few more weeks.  I’m not sure if it is because they disburse after mating, or the spring break charter trips wipe the inshore sites clean. Whatever the case, we see them all year but not in large numbers like we do now.  Many fishermen believe they are too hard to clean because of their large rib cage. But your friend that is always volunteering to take all your sheephead, is very familiar with the mild flavor and white, flaky meat.

Many underwater hunters think of early spring as the tune-up season.  Venturing to the inshore rigs and brushing up on their diving skills and getting their aim back.  Just as bow hunters start practicing with backyard targets months before bow season, spearfisherman need to inspect their rigging and practice loading and shooting their spearguns.  The difference is, spearguns cannot be shot out of the water at land targets.  The only way to practice is to get out and dive…thus the big attraction of sheephead in March.  April usually hosts the first wave of migrating cobia.  As soon as the gulf waters reach the magic 68F, we start seeing cobia on the inshore sites.  Early spring divers are always scanning into the distance, hoping to see a curious cobia head your way.

 Cobia

The smaller size and liberal creel limits on sheephead make them a great fish for new spearos to develop their hunting skills.  Once a diver has honed his diving skills, many look to add a camera or speargun to their dive plan.  Since spearing fish can be challenging and even dangerous in extreme cases, we incourage new hunters to begin with small species and work their way up to the big boys like amberjack and cobia.  The challenge of wrestling the large fish isn’t an issue with the smaller fish.  I have never heard of a diver being towed around by a 6lb. sheephead!

Call Gulf Coast Divers at (251) 342-2970 and ask about dive training and spearfishing.  Training can be completed in a couple weeks and you can be geared up and ready for this season.  A good scuba system costs about the same as a set of golf clubs or tennis lessons. But if you are like me, then you understand the real fun happens in salt water!   So don’t keep saying, “One day I’m gonna’ see what’s down there.”  Make that “One day” happen this year.

The fish, a spectacularly colored grouper, paused and opened its mouth. Finning only slightly to maintain its position just a foot (30 cm) or so above the reef, this brightly colored red and blue-spotted grouper waited patiently for another fish, a cleaner wrasse, to provide its services. Within only a few seconds the cleaner approached and went to work, moving from the tail toward the head along the grouper’s body. The cleaner paused every few seconds to pick at the skin of the grouper.

Like other cleaner species, cleaner wrasses help rid groupers and other host animals of irritating ectoparasites that can be found on the skin of the hosts. In doing so the cleaners gain a meal while the host benefits by getting cleaned.
My dive buddy and I followed the grouper as it slowly moved down the reef. We watched as another fish, the same general size and shape as the cleaner wrasse, appeared. Looking quite confident that additional cleaning services were about to be rendered, the grouper paused and opened its mouth. In the blink of an eye, the fish I thought was a second cleaner wrasse swam up and bit a chunk of skin out of the side of the obviously startled grouper.
Clearly, the attacker was a mimic, a species that does a good enough job of imitating a cleaner species to fool groupers and other fishes into thinking the mimic is the real deal. It’s a risky business to try to fool well-equipped predators, but if well-done, the act of deceit can provide a mimic with a meal. If done badly, no more meals will be necessary. This mimic was a tiger blenny, a fact that, like the grouper, I realized only after the daring blenny had enjoyed its success.
After the dive I excitedly asked my diving buddy what she thought of the scene we had just witnessed, and much to my surprise, her only comment was, “that big fish sure is pretty.” At first I thought she was putting me on, but I soon realized that she had missed both the cleaning and the attack. She had noticed that the grouper had its mouth open rather wide, but she wasn’t sure why. She thought the fish might have been injured.
Observing marine life is like putting puzzle pieces together. When you look at one fish, you see only one piece of the puzzle. Yet when you connect the pieces — say a fish to its habitat and to other creatures within that habitat — you begin to see the inner workings of a marine ecosystem.
But how does one go from fish watcher to underwater naturalist? First, the more you dive, the more you will begin to see various subtleties, and the better observer you will become. You’ll find that your awareness of the underwater world increases with time, the number of dives and the variety of habitats you get to explore and enjoy. Second, it helps to learn about what’s going on under the waves so you are more likely to recognize the happenings that you encounter during your dives.

Find Out Who Lives Where, and Why

When looking for a particular marine animal, it helps to know where to find it. Marine life identification books and regional dive guides are excellent resources for learning what types of animals you’d expect to see in a given area. Water temperature and geographical distribution are key factors in determining which species live where. For example, you aren’t likely to see a blue shark on a tropical reef. Blue sharks tend to inhabit the cooler waters of the open ocean in temperate, not tropical, seas. Conversely, you aren’t likely to see an angelfish in a California kelp forest. Angelfishes require warmer water.
Those examples might sound obvious, but being aware that within the same geographical area there are a variety of habitats, and that different groups of animals typically occur in different marine ecosystems isn’t as readily apparent to beginning divers. Keeping these facts in the forefront of your diving mind can be very helpful when it comes to becoming a better observer of marine life.
After all, it makes sense that fishes and other animals that inhabit the sand possess a different set of adaptations than do animals that inhabit reefs or live in mid-water. But because most of us haven’t had a ton of ocean experience when we first take up diving, it can be helpful to have this type of information pointed out to us.
For example, many sand dwellers have extremely low profiles. With few structures that offer hiding places in the sand biome, it should not be surprising to learn that most animals that live in the sand are excellent burrowers, able to rebury themselves rapidly if they get exposed, able to stabilize the substrate around them so they can remain in one place, or they are masters of camouflage. The behavior of creatures such as sea pens, tube anemones, clams, sea stars, sand dollars, stingrays, angel sharks, razorfishes and flatfishes illustrate these points.
In contrast, most reef inhabitants are better equipped to maneuver in the tight confines of a reef, grip the substrate, or blend into backgrounds of varied patterns and hues. Thin-bodied butterflyfishes, angelfishes, sea fans, crinoids, sculpin and other multicolored striped, spotted and mottled fishes provide classic examples that illustrate these adaptations.
Animals ranging from jellyfishes to sharks, whales, dolphins, manta rays, billfishes and tunas are better equipped to inhabit the open sea. Most fishes that live in the open ocean are designed to be superb cruisers but they lack the maneuverability of many reef fishes, and creatures such as jellyfishes would certainly be injured if they were constantly bumping into hard reefs.
On a tropical reef, the creatures encountered on the reef flat, top of a wall, shallow wall and deep wall are often different. This fact might not be so obvious the first few times you explore tropical reefs. If you are like most divers, it takes a while to get your bearings and know where you are in a reef ecosystem, much less to begin to positively identify and distinguish various species and to recognize behaviors.
In fact, I think it’s fair to say that to new divers, many marine creatures look alike. And just as a lot of marine creatures seem to look alike when you first begin to dive, it is not always immediately that different niches exist. In other words, the various niches in a coral reef kingdom or kelp forest can look the same to divers when we lay eyes on coral reefs and kelp beds for the first time. The good news is that it doesn’t take long to begin to get oriented and to recognize that different species occupy different niches within a larger ecosystem.
If you pay attention, as you gain experience you will quickly realize that the animals that occupy one niche are often different from those that occupy another niche only a few yards away.
For example, in many tropical reef systems you are likely to see schools of tangs and surgeonfishes along the tops of reefs, but you aren’t likely to find them in deeper areas. At the same time you are likely to find creatures such as lobsters, crabs, shrimps and octopods close to areas that are filled with cracks, crevices, ledges and other hiding places.
While there are way too many species to mention, you want to realize that the ocean, and even a single reef area, is not just one generic place. There are many different habitats, and different species tend to occupy the various habitats.
Of course, as soon as I make that point, I must point out that there are plenty of exceptions to that general rule. For example, you might see a school of feeding jacks, eagle rays or a reef shark cruising various niches in a reef system.
Divers that explore temperate seas will find that a variety of habitats exist in kelp forests as well as in the rocky reefs. Close to 800 species inhabit Southern California kelp forests, but different creatures live in the floating canopy near the surface, on the fronds, on and around the holdfasts, in and on the surrounding reef, in mid-water and on the nearby sand flats.
While you might encounter creatures that range in size from inch-long, rainbow-colored nudibranchs to lobsters to giant seabass on a single dive in a California kelp forest, the odds are high that you will find various species in different parts of the forest and surrounding habitats.

Consider Form and Function

The body shape of marine creatures plays a very important role in how and where various species live.
As examples, most torpedo-shaped, or fusiform, animals such as dolphins, barracudas, tunas and open-ocean sharks are built for speed. These creatures live in the water column, not on the sea floor or in the tight quarters of reef communities. Laterally compressed fishes such as triggerfishes, angelfishes and butterflyfishes are built to efficiently slip into and out of the latticework of reef formations, but on the whole they are less capable of generating the speeds attained by more torpedo-shaped animals.
Animals such as rays and angel sharks are flattened from top to bottom. These creatures are well-equipped to maintain low profiles and are typically found along the sea floor in areas where they can go generally unnoticed. These animals often bury themselves in the sand, a great way to go unnoticed by potential predators and prey alike. Armed with this knowledge, you can often discover rays and other sand-dwelling animals by noting the outline of their buried bodies.
Sea snakes and eels have a long, more attenuated shape that is ideal for slinking around in the crevices of reef communities, and that is where you are likely to find them.
By noting and considering the shapes of animals you find in very specific areas, you can begin to acquire valuable insight that will help you put together the marine puzzle. And once you begin to put part of the puzzle together, so many other pieces begin to fall into place, and that is the real payoff in being a good observer. By knowing about behaviors, lifestyle and shape, you begin to anticipate where to find various species. At that point you can pat yourself on the back a time or two, because you will be on your way to becoming a good observer.

Become Aware of Adaptations

To survive, marine animals must adapt — both to their environment and to overcome their limitations. After all, not every species can be the biggest, fiercest, fastest, most superbly camouflaged and most clever. One of the most fascinating aspects of nature and the underwater world is that there seems to be such an endless variety of adaptations that are accomplished in countless ways. Shape, as just discussed, is one of those adaptations. I’d like to point out a few more just for the sake of providing examples, but keep in mind that every animal, or closely related group of animals, possesses some adaptation, or adaptations, that make them unique. Being aware of those adaptations can be the key to enabling you to become a good observer of marine creatures.
Here are some examples. Many brightly colored animals are venomous or repulsive in some way. It’s true of lionfishes, stonefishes and sculpin. These fishes are not among the fastest swimmers. They don’t have to be. Nor are they quick to give ground when approached, because nature has equipped them with other means of defense analogous to the way that snakes and porcupines are created. When on the hunt these animals must be able to strike quickly and overpower their prey. This is equally true for other relatively slow swimmers such as frogfishes and toadfishes.
Using bright color as a warning is not unique to fishes. Many nudibranchs, shell-less mollusks that are closely related to garden slugs, have soft bodies and they are rather slow crawlers. And many species stand out prominently because of their bright colors. These nudibranchs steal the protective stinging cells of corals. Then they place them in the tissue of their own back where those cells serve to repel animals that do not pay heed to the warnings of their bright colors. In this case the colors are intended to say “leave me alone.”
In the case of other invertebrates, you will want to consider the very basic question of whether an invertebrate is permanently attached to the substrate or whether it is mobile.
If an invertebrate is mobile, can it swim like squid and octopods, does it crawl or does it simply go where wind and current take it as is the general case with jellyfishes? Because jellyfishes are at the mercy of the prevailing conditions, their stings can be quite potent. The same is true of anemones and corals. If an animal cannot pursue its prey, it better get it while the getting is possible.
Consider whether an invertebrate has a shell or hard skin. If it has a shell, what does it do when it needs to grow? Does it swap shells, as is the case with hermit crabs, or molt, as is the case with lobsters, crabs and shrimps? Some shelled animals such as snails keep their shells for life, so they need to maintain it. That is the job of their colorful organs known as mantles. Shell-swapping crabs often attach other organisms to their shells so that a host animal is less obvious.
By considering these adaptations and the challenges that each animal faces, you will gain much better insight into how different species live, who eats whom and when, where and how to find various creatures.

Hone Your Fish-watching Skills

Next time you dive, instead of simply looking at a fish, challenge yourself a little by trying to put the fish in context with its surroundings. Consider its shape and other adaptations it possesses as well as what you know about its lifestyle. See if you can determine whether the animal appears to inhabit a relatively small territory or whether it is in transit. If the fish tends to stay close to one area or repeatedly swims over the same patch of reef, look for a nest site or mate. You won’t always find them because they are not always present, but in many instances by applying a little common sense you will discover a nest, mate or perhaps a food source.
As examples, with the damselfish known as the sergeant majors that occur in tropical seas and California’s state marine fish, the garibaldi, you will often discover a male that is manicuring or protecting a nest, or trying to woo a female. It’s great fun to watch a protective damselfish attempt to ward off other egg-stealing fishes and invertebrates such as sea stars, snails and sea urchins.
If a fish is a member of a school, try to determine if the fish in the school are feeding. If they are, ask yourself if they are feeding in mid-water or along the sea floor. If they are feeding on the sea floor, as is often the case with tangs and surgeonfishes, look to see if any smaller fishes such as territorial damselfishes are trying to push them out of their territory. On the whole, damselfishes are relatively small, but they seem to have no idea that this is true. They will defend their realm against almost all intruders.
Schooling is a good way for fishes to gain access to a mate, and often in schools of hundreds, or even thousands, of jacks you will see male and female pairs, or you will see spawning activity. Next time you see a school of fish, look to see if perhaps they are feeding or if you can locate a male/female pair.
One of my favorite ways of getting oriented in any tropical reef I have not dived is to look for cleaning stations. Cleaning of some kind can be found on the majority of reef dives, and the cleaning stations are often a great place to find interesting activity that centers on fishes and some other animals. Cleaning stations are often found around prominent outcroppings such as a big coral head or sponge that is on a point. If you find cleaning activity in a given place on one dive, you will often see cleaning there again on subsequent dives.
Of course, you can conduct a similar exercise with any group of animals, but fishes are present almost every time you make a dive, and if you are a good observer, watching them closely will help you learn a great deal about the animal you are watching and about life in the sea.
Learning to be a good observer of marine life is more of an art form than an exact science. Everyone brings a different background to their diving experiences and as a group, we learn to dive in a lot of different places. After learning we travel to different places and experience different phenomena.
When you are new to diving and when diving in an area that is new to you, my suggestion is to first learn about the bigger ecosystem. Getting a grip on the big picture provides you with a frame of reference so you “have a place to put” the smaller pieces of the puzzle. By understanding the big picture you can begin to understand where, when and why you are likely to find the creatures that live in a particular ecosystem. And once you start to understand that information, it will be far easier to understand and anticipate their behaviors.

You’re Watching Them, They’re Watching You

In almost every encounter with fishes, turtles and other big creatures, it has served me well to do whatever I can to make myself appear nonthreatening and unobtrusive. For example, when I first encounter a turtle, instead of trying to get as close as I can as fast as I can, I often avoid eye contact and try to appear interested in something else. In this way I think I appear to be nonthreatening and my behavior often seems to encourage the turtle to acclimate to my presence instead of speeding off into the distance.
When observing marine life, move slowly and be patient.  Avoid chasing subjects and barging into territories like the proverbial bull in a china cabinet.  As a rule, animals will flee or hide, and even if you get close to the animal, you often fail to get the most out of the opportunity, because you have disrupted the animal’s natural behaviors.

Outside interests that are shared amongst family members usually tie that family together as they grow.  We have countless stories of families getting certified to dive for a single vacation and discovering a new weekend recreation.  When they return from an exotic locale they come by the dive shop and share their excitement, pictures and memories.  The next words out of their mouths are, “tell us about local diving”.

Water is a great “equalizer” among groups.  A family can have many different strength and ability levels and still enjoy being underwater together.  One thing I have noticed about snow skiing families is that they have discussions over breakfast about where everyone is headed and what time to meet back up for lunch.  The good skiers are bored hanging out with less experienced skiers on the bunny slope and the new skiers are scared on the more challenging runs. The result,  for everyone to have fun, is they go in different directions.  This isn’t the case with diving.  All family members can be diving together on the same reef and all get something different out of the experience.

All interests can be filled on a single dive.  The excitement and adrenaline of spearfishing for teenagers, the challenges of capturing good underwater images for dad, and the quite and tranquility for mom.

A recreation that can be shared by all and enjoyed for a lifetime.  We have many stories of 3 generations of family members diving together and developing memories that will truly last a lifetime.

If you don’t dive yet, some of what you “know” about diving might actually be wrong. A lot of these “myths’ are perpetuated in the media and movies, and you might be surprised at what is right and what myths are “busted!” Which one of these myths have you been believing all along?

MYTH: You have to be in top physical condition to dive.

TRUTH: Like any active sport, diving is more enjoyable if you’re physically fit. And you do need some basic swimming skills in order to learn. But it’s nothing extreme; if you’re comfortable in the deep end of a pool, can swim, and you can walk for several minutes without getting winded, you can learn to dive.

MYTH: Becoming a certified diver takes too long.

TRUTH: You can become a certified diver in a very short period of time, or you can take your time and learn at your own pace. Gulf Coast Diver’s VIP-PACE training program can accomodate anyone’s schedule, or you can sign up for private sessions. Our Variable Investment Program-Paced According to Capability and Enjoyment says it all.  You’ll be diving in less time than you think!

MYTH: Diving is complicated and difficult to learn.

TRUTH:  Learning to dive is easy. Our professional diving instructors use all the learning materials and proven strategies to make it simple and fun to learn. Before you know it you’ll be breathing underwater and using all the cool “toys” that make diving easier than ever.

MYTH: I’m too old to learn.

TRUTH:  We regularly hear about people diving, and learning to dive, well into their eighties. In fact one of the most active “groups” of divers is in the age range from 38 to 53. On the whole, this group dives more regularly, travels more to dive, and even takes more classes than most other “groups.”  Our own repair technician, Capt. Bill, is 77 years old and usually logs around 40 dives a year!

MYTH: I have no one to dive with.

TRUTH:  Diving is an exciting and unique experience that many people take up while on vacation or as a life-long activity. Finding buddies with which to dive is as easy as participating in one of our group dives and showing up for the regular Gulf Coast Diving Society social events. You’ll probably have ready-to-dive buddies that you’ll meet during your scuba certification course. Chances are you’ll find that you have lots in common with these other divers, usually more than the diving experience itself!  Plus, you probably have friends now that are certified divers, you just didn’t know they dove. Join Gulf Coast Dive Society on facebook and you will have dozens of dive and snorkel buddies.

MYTH: When you dive you breathe differently than you do on land.

TRUTH: Breathing naturally while underwater is one of the most terrific sensations you’ll ever experience, and one of the first things you’ll learn in your certification course. You will find that about the only difference between breathing air on land and underwater is that you must breathe through the regulator in your mouth – and since today’s regulators are so well made that breathing is made very simple and natural, even this part is easy.  You will be breathing underwater in your very first session, for only $24.

MYTH: It’s dark and murky underwater and difficult to see.

TRUTH: Most dives do not require a light since sunlight penetrates far deeper than the depth to which most divers go. Even when diving in very deep water, beyond 100 feet, divers can see quite well without any artificial light. Interestingly, colors are absorbed by the water, so while it may be very easy to see, most of the color begins to be absorbed beyond 30 to 50 feet of depth, rendering most everything blue.

Most divers do not dive in water with limited visibility unless they are looking for something special, like a lost wedding ring or an outboard motor from a neighbor’s boat. Some of these locations can give the diver the opportunity to see wrecks or find treasures, and with the proper training, limited visibility is not a significant diving obstacle. When diving from the beach the visibility will vary with the tides, but just a few miles from Mobile Bay, the clearer gulf waters will surprise you.  Or maybe, you are only interested in travel diving on vacation, each can provide their own brand of fun!

Whatever your reasons for not learning to dive, rethink them and consider giving it a try.  You can experience the thrill of being underwater for only $24, then decide whether you really want to miss out on the wonders of our oceans.

The sport of spearfishing is governed by federal and state regulations, and we have the same size and creel limits as anglers.  Spearfishing has been found to be the most environmentally friendly form of fishing due to being highly selective, having no by-catch, causing no habitat damage, nor creating stress or harm to protected endangered species.

 These facts prove a spearfisherman can harvest their catch without doing any harm to the reef, but can he actually help the health of the reef? Absolutely!

 The newest target species for us gulf coast hunters is the invasive lionfish.  The last two years has seen an explosion in the local population of these beautiful, but extremely harmful fish.  A single female can produce 1 million eggs a year and a very high percentage of those will survive.  They have no local natural predator and eat the young of all our prized species.

 For these reasons a campaign has started with divers to put our spears to work to kill any lionfish we see.  Currently, it is the only way to attempt to check this growing problem.  They can’t be targeted with hook and line, nor can they be trawled because they only live in close proximity to wrecks and reefs.  No effective idea for developing a commercial fishery has been discovered.  So far, spearfishing is the only proven way to try and keep them in check.

 We are currently conducting additional dive training for biologist with Alabama Department of Conservation & Natural Resources so they can observe the lionfish on the reefs and develop effective eradication techniques.  All in an attempt to eradicate them and protect the strong fishery we enjoy on the gulf coast.

Most anglers don’t understand the severity of the problem because they don’t see how the pyramids, tanks and natural bottom are choked with them.  Even though a mature lionfish won’t eat a large snapper, it will consume every juvenile, so very few young snapper will survive to adulthood.

 The Alabama Spearfishing Association is currently hosting the First Annual Flora-Bama Lion Fish Roundup.  This six-week tournament allows participants to win prizes by harvesting as many Lionfish as they can.  The hope is that we can harvest species and raise awareness by hosting this tournament.  Spearfishing is the only effective way to fight this battle.  All the lionfish harvested are donated to researchers that are desperate to find other means of halting the invasion.

 Call Gulf Coast Divers at (251) 342-2970 and ask about how you can participate in the fight to eradicate lionfish from our reefs.

Most of October we will see high tides during dark hours.  The best conditions for shore diving in our area are found at high tide.  Low to no current in the passes and the clearer gulf waters are pushed in close, improving visibility.  Add to this formula, a nighttime high tide and you have the perfect conditions for spearing flounder at night.

 Swimming in the gulf at night brings visions of monsters and sea serpents to the minds of the uninitiated. It reminds me of walking out of the woods after an afternoon hunt as a kid.  Every little twig snap had me gasping my last breath before a mountain lion ravaged me. After a few stressful hikes, common sense prevailed over imagination and I realized how loud a squirrel could be in the woods.   A new night diver wrestles with the same imaginings until they can relax, let there common sense kick in and start hunting for the faint outline of the fall flounder.

 Flounder are beginning their fall migration to deeper water this time of year.  It isn’t uncommon to hit the water at our preferred night dive sites and see flounder carpeting the bottom.  We have to move slowly and deliberately when they are this plentiful because every time you spear one, you will spook three.  If you see a flounder 6 feet way and swim quickly to him, it is likely that you’ve looked over the bigger one lying in wait directly under you.

Instead of wading in knee-deep water and squinting for the outline of these ambush predators, we drift along the bottom with powerful dive lights.  The southern flounder is a master of camouflage, but our bright LED dive lights will make their outline standout against the bottom.  We use a pole spear instead of a speargun.  It is similar to a gig pole, but relies on a rubber band for power instead of arm strength.

Many flounder hunters use only mask, snorkel, fins, light and pole spear to stack ‘em up.  Slipping along the beach in the surf zone, they can efficiently cover a lot a ground from the shallows down to about 5-6’ deep. This depth is out of the range of the waders.  Still others don full scuba gear and scour the deeper depths for these nocturnal predators.

During daylight hours, a flounder stays mostly buried in the sand.  But at night, they sit on top of the sand waiting for a shrimp or bull minnow to swim along, then attacking from underneath. Flounder hunting isn’t just limited to night, as the flounder move offshore to the deeper sites we scan the sand around the site for our limit of “flat boys”.

 With a minimal investment in a set of snorkeling gear, good underwater light and pole spear, you can be arriving late for work in the morning, telling stories of staying out until midnight chasing flounder in the surf zone, at night. Call Gulf Coast Divers at (251) 342-2970 and ask about dive training and spearfishing.

Now that our short red snapper season has come and gone it is time to shift back into amberjack mode.  These are the hardest fighting fish species that we target as spearfisherman.  It is because of their strength they are called “Pez Fuerte” south of the border.  In English it means “strong fish”!

 Their size and strength contribute to the excitement as the ultimate target species in underwater hunting.  Amberjack are targeted only by experienced spearos that have developed their aim well enough to “stone ‘em”.  But it only takes missing the kill spot by 2 inches to be dealt an exciting fight.  Underwater video of good and bad shots is a great tool to use in training new hunters.

 A huge trend among spearfisherman this season has been shooting video.  Most of the hunters I dive with have added camera mounts to their guns to video the excitement of the stalk, hunt and fight.

 It is easy to get a good quality, high definition video camera and underwater housing in a very small package and for a reasonable price.  The logical next step was to mount it to your mask or your gun and capture the action. Non-diving friends and family are amazed at the action and scenes that we enjoy every time we venture under the gulf. A fisherman sitting in the boat 70 feet above the action, has no idea what goes on below. The freedom of being able to select your own fish and just seeing all the species that inhabit the sites that they fish.  Instead of guessing what the colored pixels on your bottom machine represent, why don’t you jump in and have a look?

 The Sealife and GoPro-style cameras can be mounted out of the way leaving the hunter free to press “record” then forget about the camera and get on with the hunt.

The added bonus is seeing all the fish species on the reef, not just the ones biting.  The video evidence from divers has been instrumental in educating the “powers that be” on the proliferation of the red snapper population in the northern Gulf of Mexico, in hopes of getting the season and creel limits relaxed.

Divers have provided the video evidence of the Lionfish invasion to our coastal reefs.  Because Lionfish don’t bite a hook, most fisherman only read articles about the invasion.  We’ve seen the Lionfish go from a rare sighting 2 years ago, to a common species.

 Call Gulf Coast Divers at (251) 342-2970 and ask about dive training, spearfishing and underwater videography.  Training can be completed in a couple weeks and you can be geared up and ready sooner than you think. Then you can grab your Sealife camera and be uploading You Tube videos after your first trip.

Your kids get excited about Christmas morning or the last day of school, but my dive buddies and I start loosing sleep in anticipation of June 1st.  With this season promising higher fuel prices, stricter creel limits and an abundance of nice red snapper on every site, most won’t have to travel far from the dock to fill your two fish quota.  If you are like many gulf coast fisherman, who target the red delicacy, the sport of fishing isn’t really much sport anymore.  The only way to stretch your fishing day to lunchtime is to cull fish all morning.  These comments may surprise fisherman from other areas of the country that have heard we have a shortage of Red Snapper.  Well ask any Alabama fisherman and you will hear stories of limiting out in just two drops to the bottom.

Because of the restricted limits and high fuel prices, many anglers have turned to spearfishing to fill their fish boxes.  It is the ultimate in selective fishing, because you are eye to eye with the fish.  It is easier to target a particular fish and you don’t spend all day culling rat snapper.  Many fisherman complain of not getting their bait through the small snapper to reach the bottom for that big sow snapper, scamp or triggerfish.

Fuel prices are always a summer concern and with marine fuel at a premium price, running all over the gulf can be a costly technique.

I’ve been spearing on the Alabama gulf coast for over 20 years, and sat and watched many bottom rigs bounce just off the bottom with a hundred 5lb. snapper staring at it while the big un’s hang outside the commotion, exhibiting the wariness and caution that allowed them to get to 30 lbs.!

Spearfishing is also a much more comfortable way to spend the hottest months of the year on the coast.  I feel sorry for the guys I see tied to a rig, catching nothing, with sweat droplets dripping off their nose, as we hand nice fish over the gunwales to our dive buddies.

As spearfisherman, we almost always come back to the dock with full creel limits on all the usual suspects, and an average aggregate weight higher than on the fishing boats.  Our two red snapper are the first targets, and then we shift our attention to the plentiful triggerfish.  A good spearfisherman will always be glancing in the distance for a nice amberjack or curious cobia to swim along.  While cruising along the reef, wreck or rig, I am always scanning the sand for the faint outline of a flounder.  Most sites will only have 1 or 2 nice grouper eyeing the action, but mostly not participating.  The aggressive red snapper bully them away from the angler’s bait, but avoiding our spear tips isn’t as easy.

In order for anglers to target the variety of species that we fill our coolers with every weekend, they would have to take every piece of tackle in their garage.  With just one speargun I am ready to harvest whatever species is home when I visit the site.  Lockjaw because the tide isn’t right is never a problem, they may not be biting…but they are still home.

Call Gulf Coast Divers and ask about dive training and spearfishing.  Training can be completed in a couple weeks and you can be geared up and ready for this Red Snapper season.  A good scuba system costs about the same as a set of golf clubs or that custom rod with a new gold reel you’ve been thinking about.  So don’t keep saying, “One day I’m gonna try diving.”  Make that “One day” this year.

We have seen a huge increase in interest in spearfishing on the gulf coast this spring.  The warm winter and especially clear gulf waters are just the invitation many spearos need to get wet.  The main target species, red snapper are plentiful and the fish are getting bigger.  The other side of that coin is that the recreational quotas will fill faster with more large fish expected to be caught.

NOAA Fisheries Service is currently investigating a proposal that, if implemented, would increase the 2012 and 2013 quotas for commercial and recreational red snapper harvest. The quotas are expected to increase, because recent population assessments show that over-fishing has ended. The red snapper allowable catch would be increased from 7.185 million pounds whole weight in 2011 to 8.080 million pounds in 2012.  The recreational allocation will be 49% or 3.959 million pounds.

That sounds like a lot of fish, but with more anglers and spearos seeking to put filets on the grill, this quota will get filled quickly. The increased quota is a step in the right direction, but the reality…it is equal to the amount of snapper caught last year, since we exceeded the allowable limit by 730,000 pounds!  Sorry NOAA Fisheries.

In addition, if implemented, the rule would eliminate the fixed recreational red snapper closed season of October 1 – December 31. By eliminating the October 1 fishing season closure date, NOAA Fisheries Service would be able to re-open the recreational harvest for red snapper if any remaining quota is available.

 

The gulf will be a busy place on the traditional opening of red snapper season, June 1st.. The season will close 40 days later on July 10th.   And for those divers that have a competitive edge and enjoy the excitement of tournament fishing, June 1st will find them sighting down their spearguns at the wall of red snapper we have been drooling over all spring.

The Red Neck Riviera Spearfishing Tournament, held from May 18th – June 9th 2012, gives hunters 3 weeks to get underwater.  1st place Amberjack is the most sought after trophy with winning fish rarely under 80lbs. If you are primarily an “AJ” hunter, the Red Neck Riviera Tournament is your only shot at a trophy this year, since amberjack season will be closed during the Alabama Spearfishing Rodeo later this season.  The Red Snapper sizes are always impressive and promise to be even larger this year with such an abundance of fish.  A 30lb. Red Snapper may not even land a 3rd place prize in this competitive rodeo.  This is a fun tournament for all divers regardless of experience level.  Fish can be weighed 9am-6pm, mon.-sat. at Gulf Coast Divers in Mobile.

As spearfisherman, we usually come back to the dock with full creel limits on all the usual suspects, and an average aggregate weight higher than on the fishing boats.  Even if you don’t shoot a trophy fish, it still goes on the grill at home or donated for the awards ceremony fish fry.

Call Gulf Coast Divers at (251) 342-2970 and ask about advanced training and spearfishing.  You can be geared up and ready for this tournament season.  We can have you ready for the novice category in just a few training sessions.  So don’t keep saying, “One day I’m gonna try spearfishing” Make that “One day” this year.

Come celebrate Earth Day a week early. Mark your calendars for Saturday April 14th, 2012 from noon- 6pm. This event is hosted by some good friends of ours in Panama City, FL.  Everyone is invited so bring the entire family.  The plan is to focus on the “Kiddie Pool” first.  Beachcombers, waders, snorkelers and divers can all contribute to this phase of the cleanup.  When the tide is right, the divers will slip thru the “Keyhole” in the jetties and spend some time cleaning trash and monofilament from the rocks.

High tide is at 4:32 pm. Because the jetties are a popular recreation area the trash can really build up. Those who do not scuba dive are welcome to come and clean up the beach above the waterline.   This is a great opportunity to give a little back to the resource that we enjoy all year.  The event will be at St. Andrews State Park in Panama City.

Dive Problem Anticipation, Avoidance and Management training is one of the most important continuing education classes for developing self-reliance and good diving skills.  All divers can benefit from the skills learned in this class, especially divers diving from their own boat.  If you are diving without professional diver supervision (ie. from your own boat) then you are responsible for making all the decisions and need to recognize an accident or stress scenario before it happens and intervene with positive results.  Early recognition is what our divemasters and instructors are trained for and you should be too.

Some of the topics we cover in this essential class are:

  1. self-reliance and self rescue
  2. environmental awareness
  3. physical, mental and equipment preparation
  4. Pre-dive planning and complete buddy check
  5. dealing with pre-dive anxiety
  6. recognizing stress in yourself and others
  7. assisting a stressed or panicky diver
  8. accident prevention
  9. rescue scenarios and dive emergency
  10. oxygen administration
  11. dive physiology and recompression therapy
  12. “What to do if…” scenarios

As the name of the course states, problem anticipation, avoidance and management are vital skills to insure a safe, fun, stress free day on the water.  Many instructors teach a “Rescue” course, but nobody else teaches D.P.A.A. M.  This program covers rescue scenarios, but the most observant divers will address an issue before it ever escalates to a rescue situation.

For information on the next D.P.A.A.M. course call (251) 342-2970.

Maybe you are on your way to your first open water dives, or your first dives in awhile and you become aware of butterflies in your stomach. Perhaps you recognize it the night before the big day, and the apprehension keeps you from getting a good nights sleep. These are symptoms of the “pre-dive jitters”.  At one time or another every diver will experience this nervous feeling.

It is normal to be a little nervous about a new dive experience, but it’s important to recognize that butterflies are an indication that more practice and experience are needed to become a totally confident diver. The way to get this practice is by diving and continuing education.

Before your first dive, assemble your gear at home and adjust all straps, check assembly procedure and function of every item.  Having to adjust unfamiliar gear aboard a boat prior to diving can force you to rush. Rushing leads to anxiety which contributes to pre-dive nerves.

Owning your own personal gear reduces anxiety because you are familiar with it, know how it’s been maintained and have a proper fit. Proper fitting, well maintained equipment reduces stress, increases mental and physical comfort, and maximizes enjoyment.

Pay close attention to pre-dive plans and divemaster briefings and never hesitate to ask questions if you don’t hear clearly or don’t understand what was said.  If you have apprehensions, anxieties, questions or problems, please ASK FOR HELP from the group leader or divemaster. The key to overcoming pre-dive jitters is not to keep them a secret. Remember the divemasters job is to help with these issues. When informed, they will help you go at your own pace and develop your skills and confidence.

Our unique “Real-World Diving” class is a great way to learn what to expect on your dive excursions.  You’ve learned what to do underwater…this class teaches you how to do it.  Some of the topics discussed: charter boat diving, shore diving, private boat diving, how to rig your boat for diving, oil rig diving, buoy diving and international travel. New and experienced divers will learn something new in this class.

Enrolling in a continuing education course provides a great opportunity to build confidence through knowledge as well as a chance to work with an instructor to fine-tune your diving skills.  The more you dive, the more comfortable you become.  The more comfortable you become, the more fun you will have.  For information on becoming a more confident diver call (251) 342-2970.

When was the last time you practiced sharing air with your buddy?  Even for avid divers, the answer to this question is usually, “when I learned to dive”.  The next Gulf Coast Diving Society event is scheduled for sat., March 17th at Gulf Coast Divers.  We are donating the facility, pool, and divemasters to this annual event.  It is an opportunity to come jump in the pool, wash the dust off your gear, and practice all your skills.  Our divemasters and instructors are volunteering their time to insure your safety and rescue skills are top notch.  We are waiving the pool fee for all certified divers, so take advantage of this FREE event.

The Gulf Coast Diving Society is a group of divers dedicated to promoting local diving and providing a great way to meet other divers.  The GCDS will be grilling hot dogs on the deck and are excited about meeting new divers.  The event will be from 10am-4pm, with some folks hanging out all day and others coming and going.  Please rsvp to (251) 342-2970 or lewis@gulf-coast-divers.com.  The Gulf Coast Dive Society is free to all and is always looking for divers and snorkelers to help coordinate events and have fun.

Give the gift of adventure with a Gulf Coast Divers Cash Card!

Load it with any amount and give it as a Gift Card or use it yourself as your scuba shopping card.  Our Adventure Gift cards were a popular stocking stuffer at Christmas, but y’all came up with another use that we didn’t anticipate.  Divers are buying Adventure Cards and reloading them each payday as a way to save towards a new piece of equipment.  “If I keep the cash, I’ll spend it and regret it.  If I put my extra dollars on my gift card, then it is like I am saving towards my scuba system,”  explained Mike.  Great idea, dude.

The Adventure cards can be used to purchase new gear, training, a dive trip, anything…it is like cash. We know how hard it is to buy for a diver, why not make it easy and let them choose what they want? Or encourage friends and family to come and contribute to your Adventure Card rather than buy you a pair of socks that you are going to return to Target anyway.

Christmas, birthdays, anniversary, Valentine’s Day, President’s Day, Arbor Day, Just Because Day…any event is a good time to ask for dive gear.

New divers are surprised to learn that diving along the gulf coast takes place year round, not just during the heat of the summer. Believe it or not, the beaches don’t close in the winter, the Gulf of Mexico still has water in it when all the leaves have fallen from the trees and there are a lot of dedicated divers getting wet all winter.

If you want to keep diving in the winter months, but are not one of the fortunate few who can slip off to some warm and exotic location while the rest of us sit around watching our breath freeze in the air, read on and learn the basics of winter diving on the gulf coast.

So just what are the alternatives for winter diving and what can you expect for conditions? Obviously colder temperatures, both in the water and out, but not so cold that you can’t go diving. That doesn’t mean you have to gear up for an arctic expedition. Back in December we published a blog article about the importance of staying warm which provided many suggestions for dealing with winter temperatures.

Water temperatures in the gulf are a little cooler than what you are used to in the summer months. You can expect water in the low-mid 60’s at times.  Also, most of the high tides during winter months, fall at night. This is great news for the spearos that target flounder.

These tidal differences are not as much  a consideration offshore but they will affect beach dives like Perdido Pass, Fort Pickens, Destin Jetties and St. Andrews Park.  We have some of the lowest tides of the year during winter months and the strong north winds can make for especially low tides.

The local springs are virtually unaffected by winter temperatures. In other words springs water temperatures stay the same year round. The same 68 degrees that seemed cold and maybe a little forbidding in the summer is now warm and toasty.

One big consideration, just as important as staying warm during the dive, is keeping warm before the dive and getting warm between dives.  Bundle up and stay warm before you get in the water and certainly bundle up between dives. Bring a thermos of hot tea or coffee to warm you from the inside and stay out of the wind.  A misconception with inexperienced winter divers, is they will stay warm if they keep their wetsuit on between dives.  You will only make this mistake once!  The water evaporating off the suit is taking heat with it, chilling you very fast.  You will stay much warmer by getting out of your suit and dressing in warm clothes.  The more common method is to peel your wetsuit top off, dry off, and put on a jacket. Many divers exit the water, quickly peel their wetsuit off and climb back in their vehicle for a toasty, warm surface interval.

Recently my phoned chimed, announcing a text message from a dive buddy headed to the Pass for a night dive. Sorry I couldn’t make it Joe, too many work and family commitments, but it reminded me, many people are getting wet this winter and you should too.  Call Gulf Coast Divers at (251) 342-2970 to learn more about winter diving.

Well the time has finally come. Our beloved pool got it’s first facelift in almost 40 years.  It has seen thousands of divers, tens of thousands of dives and hundreds of dropped weights.

We have been talking about resurfacing for years, but it has been impossible to schedule 2 weeks that we didn’t have any classes.  As it is, we had to move the New Years week classes off until next week.  Thanks to Lewis for letting the crew in every day while the rest of us were out of the country diving.  Come by the store to view Lewis’s construction pics,  Todd’s Honduras pics, and meet the shark and turtle tiles in the pool.  We welcome suggestions for names of our new pool critters.

Wayne and Rick at Deep South Pools did an awesome job, giving up a portion of their Christmas and New Years holiday to get their crew in and get it done.

It actually took longer to refill the pool than it took for the work.  To get an idea how much water 125,000 gallons is…it took 120 hours to refill.  That’s 5 full days of hoses running full on, 24 hours a day! Anybody that thinks water is cheap, can cover our water bill for January!  Another week of filtering, heating, balancing pH, alkalinity, and chlorine and we will be up and running.

True to Atomic’s name, this mask is super-engineered and was all the talk at this year’s dive-industry trade show.

Atomic Aquatics is calling this mask the Venom, and it’s a blending of their SubFrame and Frameless masks. It has a reinforcing internal frame that’s molded directly beneath the surface of the silicone rubber skirt, like the Subframe, yet it offers the relatively low profile of the Frameless. Also, its faceplate is single window like the Frameless, but it has a high bridge and tear-drop shape similar to the SubFrame’s dual-window design.

The Venom comes across as a high-concept, stylish-looking piece of gear when it’s being held in your hand, and it’s really comfortable when mounted on your face. Its easy-to-use squeeze-to-adjust buckles are soft-mounted to the mask skirt, which allows a little bit of flexibility in strap positioning, plus they can be folded flat for packing.

Where the Venom differs from its SubFrame and Frameless cousins is in its faceplate construction. While the SubFrame and Frameless lenses use Ultraclear glass, which has quite a rep for optical quality in its own right,  the Venom mask uses an even higher-quality glass imported from Germany. Called Schott Superwite glass, it allows more light to penetrate than even Ultraclear glass.

In the water, we find a testament to a good mask is that you don’t notice it on your face. The Venom does a good job of getting there. Like its cousins, it offers a superior field of view, and the soft skirt and watertight seal combined to make the Venom feel like a part of our face. Looking at the sights through this bright distortion-free Superwite glass is like looking through no glass at all.

It’s called the Venom and the only antidote is salt water, and lots of it!  Come by Gulf Coast Divers and check it this awesome new mask, just in time for your Christmas stocking!

Even though the modern personal dive computers are very reliable and rarely malfunction, the possibility still exists.  Looking down at your computer in the middle of a dive and seeing a blank screen can be stressful sight.  Most computer issues are battery related or caused by flooding.  The flooding usually follows an improperly sealed battery compartment or a crack in the housing caused by trauma to the computer.  The problem is the crack was probably suffered in your gear bag during transport and you don’t even realize it until it is too late.

Because of the possibility of a dive, or entire dive day, being ruined because of a computer issue, most divers dive with 2 personal computers.  Oceanic’s new B.U.D. (Back-Up Dive) computer is the perfect addition to your dive kit.  It clips to your B/C and tracks all your dive info. and can be used as a primary computer, quick-glance status, back-up or spare.

The B.U.D. is small enough to clip to any d-ring on your B/C and you will hardly even know it is there, but has an easy to read display.  It has full computer functions, including nitrox compatibility.  Economically priced at $329.00.

The power went out a couple of mornings ago which sent me searching for a flash light. Showers can be awfully dark at 5:30am. The only flashlight with good batteries I could lay my hands on was a crevice light from my dive bag.  Like many divers, and every dive instructor I know,  those new household lights must do double duty as dive lights.

You might think buying a new light would be very simple, but there really are a lot of things to consider. There are hundreds of lights to choose, so you will have to do some weeding out to come up with the one that is right for you. To get started you should set up a list of criteria, that will, hopefully, sort  the scores of lights available and bring you down to your ultimate choice. Here are few considerations to get you pointed in the right direction:

  1. Type of diving you do (day, night, cavern, cave, wreck)
  2. Lights you already own (crevice, full size, canister)
  3. Type of bulb (Halogen, Xenon, LED, HID)
  4. Battery type (standard, lithium, rechargeable)
  5. Size/ Power (1.5W- 15W)
  6. Price ($15-$1000)

If midday dives are all you do, you might be thinking you don’t even need a light. My personal feeling is, if you aren’t diving with a light on every dive you are missing out on more than you realize. Virtually every dive site is loaded with nooks and crannies that hide strange and fascinating creatures just waiting to be discovered. Without a crevice light all you see when you peer into that crevice is darkness. A small crevice light, that easily fits in the pocket of your BC is all you need to reveal all of those hidden critters. In addition, since reds and oranges are filtered out of natural light at very shallow depths, most dives appear blue-green. You will be surprised how colorful that “green” reef really is when you shine your light.

Night dives require something more than your small crevice light, although that light can be a sufficient back-up. With the advances in LED technology your primary night light selection is no longer limited to huge honkin’ light cannons. Technology has contributed to more light in a smaller package. Before the advent of LED light technology, brightness and power depended on battery size. The really powerful dive lights held (8) D cell or lantern batteries that you really needed to consider part of your weight system.

Light gloves are becoming very popular with divers seeking hands-free illumination.  Whether a canister light (separate battery pack and light head) or traditional light, I recommend having a back-up, if you rely on it.  Cave divers and night dives require light to dive safely, so a minimum of 3 lights is standard.

Whether it is hand held, clipped on your BC, head mounted or attached to a speargun, it has to work.  Check your batteries the day before you dive, so you have time to purchase new ones if they are weak.  I have robbed batteries out of radios and household lights to power a dive light at the last minute.  I don’t like rechargeable batteries because they discharge while being stored and give little warning before dying.  Traditional batteries become weaker as they discharge which dims the light.  This is my warning to deploy a back-up or plan on replacing batteries soon.

Dive lights can be as little as $15 and go to over $1000 on some canister lights.  Call Gulf Coast Divers (251) 342-2970 and talk to a light expert about the best light for your diving style.

Spearfishing can be an exhilarating way to put seafood on your family table.  It is, without question, the most selective way to harvest fish with very few lost fish and zero bycatch.  We spearos have a responsibility to land most of the fish we shoot, which means minimizing lost fish due to “tear-out”.  If a strong fish is shot in the belly or if the spear didn’t penetrate far enough through the fish, that fish may tear off, swim away and die.  A powerful, accurate speargun can help reduce this type of loss.

The most common reason for lost fish is a poor shot.  Choosing the right speargun for your hunting style and locale will maximize your results and increase your enjoyment.  Using the proper tip, such as breakaway and slip-tips, also helps reduce lost fish.  Ideally, you may want a variety of different guns to suit the various types of hunting conditions you will encounter.  Some of the things you should take into consideration are water clarity, game size, proximity to fish and gun rigging.  I use a pole spear for flounder and shore access dives because it is easier to handle around jetties, fish species are smaller and visibility can be limited.  You never want a gun that will shoot outside of visible range.  I recommend a 36” to 42” gun for smaller game fish such as triggerfish, scamp, black snapper and sheephead.  These species usually allow for closer approach which reduces the range the gun has to propel the shaft.   If your target species are amberjack, cobia and red snapper you will want more range and power and a 48” to 52” gun may be more appropriate.

The best way to become a good “spearo” is to dive with spearfisherman and watch how they approach, shoot and string fish, then dive alot and practice those skills.  Before you can become a good hunter, you must be a great diver.  New divers ask me often to recommend a number of logged dives as a goal before picking up a gun.  My answer is, there is no magic number.  A more accurate determination is skill level.  When you shoot your first fish, your attention will automatically zoom in on that fish and the fight.  But, you can’t forget about air consumption, depth, time, navigation, proximity to buddy and ascent rate, to name a few.  My recommendation is don’t start diving with distractions (spearguns, cameras, scooters) until your fundamental dive skills are automatic.

The points above are just a few of the topics discussed in our spearfishing class.  I will discuss general information for spearfishing on the gulf coast and equipment specifics relating to guns and local species in this series.  I will try to post a new article every week discussing different spearfishing topics.  Watch this blog for new articles and call me at (251) 342-2970 to ask questions on these or any other discussion topics.
