B2 Regulator
Brass & Titanium Regulator
US$949.95 – US$999.95
COMFORT. PERFORMANCE. STYLE. AND VALUE.
Our most popular regulator, the Atomic Aquatics B2 system combines the signature second stage design and materials of the T3 with a Chrome-plated Brass first stage. The result is an incredibly high-performance regulator system that is approachable for every diver and every budget.
B2 Brass & Titanium Regulator
HIGHLY AWARDED. HIGHLY REGARDED.
The Atomic Aquatics B2 has garnered more awards from independent tests and reviews than any other regulator on the market. And the B2 has fans in virtually every corner of the dive industry. The signature breathing performance of the T3 was engineered into the B2 with virtually the same corrosion-resistance. The difference is the metals used in the first stage, which are more economical without sacrificing performance. And the B2 ergonomics make it the world’s most comfortable second stage, just like the T3.
PATENTED AUTOMATIC FLOW CONTROL
You shouldn’t have to think about breathing when you dive. The exclusive Atomic AFC helps you breathe naturally at any depth without thinking about making adjustments. The Atomic AFC eliminates the manual adjustment normally needed to regulate Venturi effect as you dive deeper. No dials to turn or buttons to push. A Rapid Adjustment Knob is included for special situations like surf entry or octo use. (US Patent No. 5,678,541)
PATENTED COMFORT SWIVEL
Divers also shouldn’t have to worry about turning, twisting or looking over your shoulder. The popular Atomic Comfort Swivel removes that concern by allowing 30° range of motion without hose binding, pulling or kinking. The B2 Comfort Swivel is polished Stainless Steel with black PVD coating. (US Patent No. 7,188,869)
The Most Awarded Atomic Regulator
Virtually identical performance as the T3 with a Brass First Stage The B2 gives divers a close alternative to the all-Titanium T3. The signature Atomic breathing performance is nearly identical. The B2 is ergonomically designed to be the world’s most comfortable second stage just like the T3. The key difference is the chrome-plated Brass body of the B2 first stage, which is more economical without sacrificing performance. That’s why the B2 has garnered more awards from independent tests and reviews than any other regulator on the market.

2-YEAR / 300-DIVE SERVICE INTERVAL
LIMITED LIFETIME WARRANTY
Which mark will you hit first? 2 years or 300 dives? You won’t even need think about recommended servicing until then. And the Atomic Aquatics warranty is NOT contingent on proof of service. Metal parts are warranted against corrosion for life. Period.
The key to the success of the Atomic Aquatics brand seems to be not to make things particularly different but to make them better. The B2 is a second-generation design which combines a new second stage that has an all-Titanium mechanism with the previously available B1 chromed brass and 316 stainless-steel first stage. I never found this regulator wanting in the amount it could supply, yet it was discreet and subtle in its delivery. There were no sudden and dramatic rushes of air – it flowed. It was sublime. Added to the fact that it is a jewel in the way it is made, any purchaser is likely to be a proud and long-time owner.

APRIL 2004
Atomic Aquatic’s B2 breathes effortlessly on the simulator, regardless of RMV or depth. But this isn’t just a laboratory reg. The B2 earned the highest total score for in-water performance of any reg in any price. It breathes easily in all positions and is the only reg to earn an excellent score for dryness. The B2’s dual silicone mouthpiece, introduced last year, is still a favorite among testers.

This 2003 Testers’ Choice breathed effortlessly on the simulator, delivering perfect scores on ScubaLab’s standard tests. When pushed to its limits, the reg was able to achieve a breathing rate of just a tad over 75 RMV. Take the B2 into the water and it breathes easily in all positions and is dry as a bone.

Atomic B2/M1/Z2
True to Atomic Aquatics claims, the redesigned B2 and M1 did deliver improved work of breathing on the simulator, although this improvement simply puts a shine on what was already stellar breathing performance. The Z2 effortlessly kept pace with its higher-priced brethren.
When the regs were taken out for some real-world diving they proved to be sweet breathers in all positions. Test divers considered the B2, Z2 and M1 to be the driest breathing regs in this year’s go-round. The regs come with a two-year/300-dive service interval, and the limited lifetime warranty is not contingent upon annual servicing.

Jeff Albinger –
Been diving since 1972, I’m also an O/W Instructor. This is probably the best breathing regulator I’ve used. I love the swivel on the 2nd. Stage!!
Chuck Rawlinson –
We just got back from the Florida Keys and dove with our new Atomic B2’s. Best breathing regulator I’ve ever used. Flawless.
