Designed as premium regulator in the Atomic range the B2 is recognised by many as the work horse of the atomic range.   A regulator without peer, it has won multiple industry awards including the coveted ScubaLab Testers Choice in the high-performance regulator category.  The B2 First stage is built almost entirely with chrome plated brass, an exceptionally robust and hard metal renowned for its corrosion resistance, making it perfect for use in both saltwater and chlorine environments.  Due to this corrosive resistance and the hardwearing material, Atomic offer the industries’ best service interval of 2 Years or 200 dives. This regulator is built to go year after year without any drop in performance.  The Lifetime warranty is also unique in that it is not reliant on service and is transferable to the next owner. 

Internally the B2 utilises a high flow piston which efficiently regulates the tank pressure exactly dive after dive.  The low-pressure ports are housed on a swivel turret to allow for perfect hose routing.
