Atomic Aquatics B2 Regulator is a lightweight regulator with a brass first stage design, and a great alternative to Atomic Aquatics T2 regulator without sacrificing performance. This regulator is ergonomically designed to be the world's most comfortable second stage. The B2 shares the identical first and second stage design and performance as the T2; the main difference is a chrome-plated brass body of the first stage, which is more economical without sacrificing performance. Exactly the same performance as the Atomic T2 regulator, with a first stage crafted in a more affordable material and only 9 oz. heavier than the T2.
