Demanding dives require heavy-duty gear. The Octopus Abyss Extreme is an all metal backup breathing apparatus that matches perfectly with Mares' line of all-metal regulators. With a special fluoropolymer resin finish, all the key components are protected from ice crystals forming during extremely cold conditions.
Mesh Grid: Patented design that reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents
Superflux Hose: Lightweight and soft for pliable movement
All Metal Technology: Outstanding mechanical resistance and high thermal conductivity make the metal 2nd stages extremely long lasting and ideal for cold water dives. The high thermal conductivity of metal reduces dry mouth during the dive
Vortex Assisted Design (VAD) System: The air bypass tube sends air to the mouthpiesce creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very easy breathing at all depths. In cold water diving, this system prevents ice crystals (which can be generated by the expansion of humid air in cold temperatures) from interfering with the proper operation of second stage components.
