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

The Atomic Aquatics B2 Regulator package combines a T3-inspired second stage design with a chrome-plated brass first stage and all-titanium construction elements, delivering reliable performance for scuba diving. The pneumatically-balanced design promotes smooth breathing across depths and tank pressure, supporting underwater exploration as part of a complete scuba gear setup with the included Yoke and Color Kit plus Z2 Octo.

Built for durability and consistent breathing, this package emphasizes materials and design that are trusted by divers. The chrome-plated brass first stage with 316 stainless components and all-titanium construction, along with a high-flow Jet Seat piston, provides stable airflow at varying tank pressures. The system is Nitrox-ready for mixtures up to 40%, includes a factory-sealed option to guard against silt and sand, and offers accessible tuning with a soft overmolded Rapid Adjustment Knob and an Atomic AFC for stable performance underwater.

The Z2 Octopus complements the B2 regulator with precision-machined brass, zirconium plating, and titanium components, plus a Titanium Seat Saving Orifice and Atomic AFC. A high-flow second-stage case reduces breathing effort across a wide range of depths, and a rapid adjustment knob allows manual detuning as needed. Optional color kit allows personalization of the diving gear while maintaining underwater performance.
