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.

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!!

We just got back from the Florida Keys and dove with our new Atomic B2’s. Best breathing regulator I’ve ever used. Flawless.
