The Atomic Aquatics B2 Regulator, DIN sealed with color kit, pairs the trusted second-stage design of the T3 with a robust first stage to deliver smooth, reliable breathing across scuba and diving environments. Built for underwater performance in saltwater and mixed-gas scenarios, this regulator system remains approachable for divers while maintaining high-end durability and steady airflow.

Designed for practical use in underwater gear setups, the B2 emphasizes corrosion resistance, tuning stability, and easy maintenance. Its configuration supports reliable operation across depth changes, tank pressures, and surf entries, with options to customize its look through an optional color kit.
