Atomic B2 Regulator

Atomic B2 Regulator


The Atomic B2 Regulator is ergonomically designed to be the world’s most comfortable second stage. The Atomic B2 Regulator is the next generation of the highly acclaimed Atomic B1 regulator. The Atomic B2 Regulator has received more accolades from the diving press and independent test reviews than any other regulator in history for both performance and ergonomics. The Atomic B2 Regulator shares the identical first and second stage design and performance as the T1, the most notable difference being the metal (titanium) used in the T1. The Atomic B2 Regulator matches the industry’s only all-titanium second stage with a compact high performance first stage of chrome plated brass and type 316 stainless steel. The second stage is so light in your mouth it almost floats.

The Atomic B2 Regulator by Atomic Aquatics features Titanium Construction, Comfort Swivel Hose, Seat Saving Orifice, Automatic Flow Control, Dual Silicone Comfort Fit Mouthpiece, Impact Resistant Two Tone Second Stage Housing, Compact First Stage Design, Nitrox Compatibility and High Pressure Piston Seal System. The titanium construction, for the Atomic B2 Black Regulator, allows for ultimate corrosion resistance and is light weight to eliminate jaw fatigue. The comfort swivel hose allows unidirectional movement without loss of performance. It will eliminate any pulling of the second stage.
