Introducing the Atomic BC1

SCUBA boards online have been buzzing with rumors and chatter about Atomic Aquatics’ first BC for more than ten years now. That’s how long it has taken the luxury brand to perfect the first BC worthy of the Atomic name.

Atomic Aquatics doesn’t rush anything. They prefer to take their time and carefully craft the toughest and most user-friendly dive gear on Earth.

Just as they redefined regulators, masks, and fins with careful attention to design details, Atomic re-examined every BC feature to create the most durable, long lasting, and high performance model the market has ever seen.

We are excited to say that the long wait is finally over; the new world-class Atomic BC1 BCDs are here.

The Atomic BC1: the BCD worthy of the Atomic name is finally here

What makes Atomic Aquatics BC1 so special?

Revolutionary tank cam and pad

The ratcheting tank band design sets a new standard for easy and always secure BC mounting.

Atomic engineered this completely different mounting hardware using principles from ski boots and snowboarding to create an easy to use system featuring a tightly locking, over-center buckle band.

This is simply the best and most user-friendly tank cam system ever.

In addition to the ratcheting buckle band, there is also a tank positioning strap and a non-slip, molded tank pad built in to the back of the BC, complete with CNC-Machined Stainless Steel hardware. This system eliminates the pesky rubber non-slip strip found on other tank bands.

These features combine to make mounting easier than ever before while also ensuring the end of slipping tanks, repeated adjustments, threading buckles, and the usual trouble of changing cylinder sizes. No existing tank cam band has even come close to the ease of operation of the BC1.

We think this game-changing feature alone makes this the BCD of choice, but that’s not all. The high-performance BC1 introduces several other new features that set it apart:

Water resistance

The state-of-the-art matte fabric is laminate coated on both interior and exterior and as water resistant as a raincoat. Yet it is remarkably soft to the touch. It’s something you’ll have to feel for yourself.

Other BCs promised to be quick drying; the Atomic BC1 never seems to get wet at all.

The laminate layer is thicker on the outsides to increase durability by protecting against rips, tears, and leaks.  It’s so tough that it will accommodate nearly double the pressure of other BCs.

Sand and corrosion resistance, too

The large accessory pockets feature zippers that are self sealing to prevent sand from filling pockets or gunking up zipper teeth.  Mesh pocket interiors drain easily.

D-rings are conveniently placed inside these oversized pockets to secure things. Keep your stuff securely attached while using it, without having to undo and reattach.

All D-rings are 316 Stainless Steel and coated with PVD Titanium to resist salt water corrosion. Atomic generously  and strategically placed these for convenient attachments. For example, The D rings along the bottom edge are tucked neatly behind the pockets, rather than dangling from your BC.

EZ-LOK weight release system

The EZ-LOK weight system is another feature that you need to see and experience for yourself to fully appreciate how much Atomic has improved what a BCD can be.

Atomic fins are favorites because everyone loves their EZ-LOK fin straps. The BC1 uses this exclusive patented system to eliminate any struggle with integrated weights.  They are secure, easy to release, and loading the weight pockets into the BC is a snap.

Weight pouches glide in smoothly, snap to lock in place, and easily release with a tug on the handle. They are so easy that you can operate them using just one finger, but they snap securely into place, so you’ll have no worries about accidental release.

The weight system on this BC is versatile and super easy to use: each pouch holds up to ten pounds of hard or soft weight. The pouches that come with the XL will hold up to 14 pounds.

There is also a pair of additional, non-releasable, integrated weight pockets in the rear. These hold between six and ten pounds each, depending on jacket size. The placement of these trim pockets significantly improves diver profile underwater.

Maximum comfort and adjustability

The BC1 features a large area of elegant diamond-quilted back padding and an adjustable lumbar pad, making this the most comfortable BC available.

There is also a convenient carry handle.

It offers three planes of adjustability for a custom fit.  The BC1 includes torso, sternum, and waist straps with impact resistant easy side release buckles.

It also has an adjustable cummerbund for added comfort, security, and fit.

Patent-pending exhaust pull dump technology

The two Stainless Steel Dry Glide pull dumps have extra long cords and patent-pending Anti-Float Pull Knobs for easy reach.

Inflator options

The Atomic inflators are sold separately. This gives you a choice of high performance options.

Your choices:

You could choose Atomic’s innovative corrosion resistant Ai power inflator, which comes in both Stainless Steel and premium Titanium options. These are the best and most diver-friendly power friendly inflators in the world.

Or you could ditch your octopus and opt for the Atomic SS1 in Stainless Steel or Titanium. This revolutionary device couples a power inflator with a secondary regulator that breathes like a primary. It features ergonomic controls, a low-profile design, and incorporates Atomic’s patented seat-saving orifice that prevents problems and leaks, as well as doubling the service cycle from annual to two years. It also has an integrated purge cover, a lifetime warranty, and more.

While some may balk at the Atomic price, the BC1’s rugged durability, elegant design, and user-friendly features offer tremendous value that will outlast and outperform any other BC on the market.

We invite you to come by the shop to check out this beauty for yourself. We’re here 9am-6pm Mon-Sat.  Bring your swimsuit and take it for a test dive in our pool.

What are 6351 cylinders?

Aluminum 6351-T6 is an alloy that was previously used for SCUBA and SCBA cylinders. There is a problem specific to that alloy that makes them potentially very dangerous,so most fill station operators will not fill them. This is an old problem, but there are some of these cylinders still around and many divers are unaware of the dangers.

Several companies produced and distributed these, including Walter Kidde, Luxfer, and Cliff Impact.  Many millions of these high-pressure cylinders were produced from this alloy. It was discontinued for these by 1990, due to a metallurgical anomaly which can cause sustained load cracking (SLC) along the neck and shoulder areas.

SLC: an explosive problem

SLC cracks tend to develop slowly over several years, most frequently in tanks that have been stored full of air. SLC has caused the explosive rupture of many of these cylinders and multiple losses of life and limb.

Before the technology to electronically detect this problem was invented, we had one of these cylinders explode in our store during a fill. The force of the explosion tore a hole through the roof and knocked a chunk from the concrete slab floor. Damage to the steel frame of the basketball hoop hanging over our pool is still visible today. It was caused by just a small piece of the cylinder hitting the heavy gauge steel and shredding it apart. Luckily, no one was hurt.

This happened with many of these tanks, both in the US and abroad. In some cases, such as the incident in our store, the explosions caused damage but did not result in injury. In other cases, they caused serious injuries and even death.

The explosive problem occurred often enough to warrant a DOT investigation, which resulted in advisories and warnings but no recall. However, we know the problem has been understated. For example, the explosion at GCD has not been included in the known SLC explosion data reported by Luxfer, though we reported it when it occurred and then again later brought it to their attention that it was not included.

Luxfer, who produced most of these cylinders, switched to a proprietary 6061 alloy and phased out the use of 6351 completely in June 1988. They issued several bulletins regarding the SLC problems and offered replacement incentives for many years in an effort to get these older cylinders out of use.

Eddy Current Testing

Because of this significant issue, a new method of tank inspection, eddy current testing, was developed. You may have heard this referred to as VIP Plus, which is a specific brand name. The visual only method previously employed for tank inspection is no longer sufficient for testing, thanks to the metallurgical anomaly associated with the 6351 alloy. Eddy current machines use electronic waves and can detect cracks that are invisible to the eye.  DOT rules now require electronic eddy testing at the same time as hydrostatic requalification, but manufacturers recommend eddy current more often.

Dive Stores and fill stations are well aware of all this and have been for many years. Both the US DOT and NIOSH released multiple detailed safety advisories. Luxfer addressed the topic in several ways, including a seminar at DEMA, the largest annual diving industry trade show, and this may have been the most attended meeting in DEMA history. The room was packed full to standing-room only, and attendees overflowed into the hallway as well.

Do you have 6351 cylinders? Here’s what to do

Many individual divers, however, were not, and some still are not, aware of this significant problem. If you have aluminum SCUBA cylinders manufactured by Luxfer prior to July 1988, or any Walter Kidde tanks, they are likely 6351 cylinders. There are almost no fill stations who will agree to refill these now. While GCD does not have a store policy against this, we will not force our employees to do so. Due to their advanced age and the well known issue of SLC, we prefer not to fill them. As stated above, we have already had one of these tanks rupture and explode in our store.

In an effort to get these bottles out of use, we will issue a $40 credit toward the purchase of a new tank for each 6351 cylinder trade out.
