The Atomic 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.

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)
