The Abyss Navy II Regulator Set is engineered for high-performance diving in extreme conditions. The first stage features high-flow, pre-oriented DFC outlets and includes a cold water kit, making it ideal for cold water and deep diving. Tested and approved by the US Navy, it has passed rigorous standards, including dives at 60m depth in -2C water with a 62.5 l/min breathing rate and 170 bar cylinder pressure. The second stage is coated in a durable fluorinated polymer resin and uses VAD (Vortex Assisted Design) for smooth, natural breathing. Its Mesh-Grid system enhances performance in strong currents, making it exceptionally reliable for cold water diving. Paired with the Ultra Adj Octopus, made from ultra-lightweight technopolymer and equipped with a Twin Power System and PAD (Pneumatically Assisted Design), this setup ensures customizable airflow, effortless breathing, and maximum comfort at any depth. A Superflex hose adds flexibility and support for every dive.
