Product Information


Abyss Navy II First Stage
The Abyss Navy II first stage is highly reliable even under extreme diving conditions. Equipped with high flow rate, pre-oriented DFC outlets. The regulator comes with a special kit for dives in especially cold water. This first stage is approved by the US Navy since it has passed the high standards required by the US Naval Forces. It was specifically tested on extreme dives (30 minutes 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).

Abyss Navy II Second Stage
The Abyss Navy II second stage is covered with a special fluorinated polymer resin finish. It features a Vortex Assisted Design (VAD) system that enables a dynamic airflow, ensuring natural and easy breathing at any depth. The lid features the Mesh-Grid system to optimise water inlet and outlet flows, which offers 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.

    All Metal TechnologyOutstanding mechanical reliability 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 also the dry mouth feeling during the dive.

  3. VAD - Vortex Assisted Design
    VAD - Vortex Assisted Design

    VAD - Vortex Assisted DesignThe air bypass tube delivers 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.

  4. DFC - Dynamic Flow Control

Please follow the instructions contained in the manual. You must read and understand all warnings and instructions in their entirety before using our products. Scuba diving is a hazardous activity, which involves a risk of injury to any and all parts of the body. As with all scuba diving equipment, our products are designed to be used by trained, certified divers only.

Regulator Special Disclaimer
Equipment complying with EN 250 is not intended for breathing by more than one user at the same time.

If SCUBA equipment is configured and used by more than one diver at the same time, the cold water and breathing performance may not fulfill the requirements of EN 250. Therefore, the octopus should not be used during dives in cold water. Use of the dual regulator is recommended for cold water diving.

For safety reasons, it is not advisable to use an Octopus second stage that is not a certified Mares Octopus.
