- Experience exceptionally smooth breathing, premium comfort and outstanding durability with the Atomic Aquatics B2X DIN Scuba Diving Regulator. Building on the performance of the renowned B2, the B2X introduces Atomic Aquatics’ advanced Diamond-Like Carbon coating for superior protection in demanding marine environments.
- An exclusive balanced Jet Seat high-flow piston delivers stable intermediate pressure and dependable airflow, even as cylinder pressure falls. The rotating first-stage swivel cap provides flexible hose routing, while the secure 300-bar DIN connection creates a compact regulator setup ideal for recreational and advanced diving.

Combined with the dual-silicone comfort mouthpiece and low-effort exhaust system, the B2X delivers excellent comfort during both relaxed recreational dives and longer underwater adventures.
