All Metal for maximum performance
All metal technology second stages have superior performance over plastic second stages, especially in cold water, due to the high thermal conductivity that limits the freezing effect. Additional benefits are the improved durability, the longer working life and less dry mouth from breathing compressed air. This all metal octopus is made of marine grade brass and then coated with a special fluoropolymer resin finish on the second stage case and all key components to prevent ice crystals from forming in extreme cold conditions.
The patented mesh design of the second stage cover reduces the pressure of water flowing onto the regulators diaphragm and minimizes free-flow. Even in a strong current it eliminates the need for a knob to de-tune your air delivery system- advance technology through basic physics.
All Mares second stages are a reliable downstream valve design and offer the unique patented Vortex Assisted Design (VAD) system. 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.
Mares developed the Superflex hose after many years of testing and research. The results achieved far surpassed the tests required by EN250. Hose is extremely light weight and exceptionally soft, guaranteeing the maximum freedom of movement and reducing jaw fatigue. Mares Abyss Extreme Octopus comes with a limited lifetime warranty.
