Atomic Aquatics B2 Swivel Regulator, DIN, Black

Ergonomically designed to be the world's most comfortable second stage, the B2 is the next generation of the highly acclaimed Atomic Aquatics B1 regulator. The B1 regulators have received more accolades from the diving press and independent test reviews than any other regulator in history for both performance and ergonomics. The B2 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 B2 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 B2 is a balanced flow-thru piston design using Atomic Aquatics jet seat high flow stainless steel piston. Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance. The Atomic Aquatics jet seat system has no sharp edges that can damage the seat over time, like most competitors' first stages. Instead, Atomic Aquatics employs a conical seat and blunt end piston. Atomic Aquatics' valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure. The B2 is also freeze protected with a factory sealed first stage th
