Atomic Aquatics B2x Unsealed Black is a high-performance regulator set designed for scuba and diving applications. The first stage features a Diamond-Like Carbon (DLC) coating over chrome-plated brass, delivering superior wear resistance and corrosion protection while maintaining smooth operation underwater.

The B2x system combines an all-titanium second stage with an ergonomic first stage and a pneumatically-balanced poppet for easy breathing at all depths and tank pressures. It is Nitrox ready, approved for non-dedicated EAN use with mixtures up to 40%, and includes an option to seal at the dealer to prevent outside contamination from silt and sand—keeping your scuba gear performing reliably in underwater environments.

Designed for straightforward maintenance and reliable performance, the B2x Unsealed Black offers consistent air delivery, a comfortable mouthpiece, and a compact, durable package suitable for both novice divers and experienced divers exploring underwater environments.
