Amazing performance at an AMAZING price!

Our most popular regulator, the Atomic Aquatics B2 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.

The B2 octo incorporates the same patented Atomic Aquatics features that make our primary regulator models the best in diving. The Atomic Aquatics AFC Automatic Flow Control and Titanium Seat Saving Dynamic Orifice are identical to the B2 primary second stage. The B2 Octo includes a high-visibility Neon Yellow cover and extra-long 36” hose and has a swivel.

Sealed first stage to prevent outside contamination from silt and sand, or freeze-up in cold water conditions.

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.
