Atomic Z3 Swivel Diving Regulator

Atomic B2 Swivel Diving Regulator – Designed to be the most comfortable second stage in the world

Ergonomically designed to be the most comfortable second stage in the world, the B2 is the next generation of the acclaimed Atomic B1 regulator. B1 regulators have received more praise from the diving press and independent test reviews than any other regulator in history, both for performance and ergonomics.

The B2 shares the same first and second stage design and performance as the T1, with the most notable difference being the material (titanium) used in the T1. The B2 combines the industry’s only all-titanium second stage with a compact, high-performance first stage made of chrome-plated brass and 316 stainless steel. The second stage is so light in the mouth that it almost floats.
