Diving regulator Mares Abyss 22 NAVY II

Diving regulator Mares Abyss 22 NAVY II

1st Stage

The Abyss Navy II first stage is highly reliable, even under extreme diving conditions, and is equipped with high flow rate and pre-oriented DFC outlets. It includes a special kit for cold water dives. This first stage is approved by the US Navy, having passed the stringent standards required by the US Naval Forces. It was specifically tested on extreme dives (30-minute duration, 60m depth, 62.5 l/min ventilation, -2°C water temperature, 6-minute ascent in both fresh and salt water, constant cylinder pressure of 170bar).

2nd Stage

The Abyss Navy II second stage has a special fluorinated polymer resin finish. It features a Vortex Assisted Design (VAD) system that enables dynamic airflow, ensuring natural and easy breathing at any depth. The cover features a Mesh-Grid system to optimize water inlet and outlet flows, offering further improved performance even during strong currents while diving. The Abyss Navy II second stage is reliable, durable, and ideal for diving in the most extreme cold water conditions.

Technologies

Mesh Grid: Patented design which reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents.

DFC- Dynamic Flow Control: Minimizes intermediate pressure drop during inhalation thus maximizing gas delivery, especially under extreme conditions.

VAD-Vortex Assisted Design: The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low-pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.

All Metal Technology: Outstanding mechanical resistance and high thermal conductivity make our metal 2nd stages extremely long lasting and ideal for cold water dives. The high thermal conductivity of metal reduces the dry mouth feeling during the dive.
