Introducing the Abyss 22 Navy II, Mares' answer to your diving needs in any condition, even under ice. Careful analysis and design ensure top performance and reliability in the toughest environments.

The first stage of this all-chrome-plated marine brass regulator features a balanced diaphragm design that's environmentally sealed. This design prevents contaminants like salt, sand, and chlorine from entering the internal mechanism, ensuring lasting performance without corrosion or mineral deposits.

The Navy 22 Abyss II goes a step further with the CWD kit, keeping cold water from the spring cavity and ensuring consistent air flow. Its Tri-Material Valve Technology optimizes performance, safety, and reliability. A hard Polyurethane (PU) covers the valve, while a soft PU layer ensures a perfect seal for unmatched durability.

The first stage also includes Dynamic Flow Control (DFC), minimizing intermediate pressure drops for a simpler, more reliable second stage without manual adjustments. This guarantees stable air flow in extreme conditions.

The all-metal second stage, made of marine-grade brass with a fluoropolymer resin finish, outperforms plastic alternatives in cold water due to high thermal conductivity that limits freezing. Additionally, it offers improved durability, longer working life, and reduced dry mouth.

The patented mesh design of the second stage cover minimizes free-flow and negates the need for de-tuning. Mares' patented Vortex Assisted Design (VAD) system ensures sensitive and easy breathing at all depths.

The Abyss 22 Navy II passed the U.S. Navy Experimental Diving Unit (NEDU) tests and is now authorized for military use. Weighing 47.2 oz (1337g), it comes with a 29.5" (75cm) low-pressure hose and features multiple ports for optimal performance. The regulator is Nitrox-ready up to 40% oxygen, straight out of the box.
