Atomic Aquatics B2 Regulator, DIN with Color Kit and Z2 Octo Scuba Diving Package

The Atomic Aquatics B2 Regulator, DIN with Color Kit and Z2 Octo is a complete scuba diving regulator package designed for comfort, performance, and value. The B2 system blends the signature second-stage design from the T3 with a chrome-plated brass first stage to deliver reliable breathing across a range of diving conditions. Built for saltwater gear setups, it emphasizes durability and smooth airflow for scuba and underwater exploration.

Key design elements include a pneumatically-balanced poppet and high-flow case for easy breathing at all depths, an Automatic Flow Control (AFC) to maintain stable breathing characteristics under varying conditions, and an optional factory-sealed design to prevent outside contamination from silt and sand during dives. Nitrox-ready up to 40% for extended diving capability, it provides multiple ports (2 high-pressure fixed and 5 low-pressure on a swivel cap) for flexible hose routing. The hose features a polished 316 stainless steel Atomic Comfort Swivel with Black PVD coating for durability and comfort, and a dual-material second stage cover designed for full-front purge and grip.
