Product Overview

Abyss is a high performer in cold water and available with the compact MR52 first stage: the best for a unique high caliber set up. The Double Dynamic Flow Control system provides a consistent flow of air at any depth, even when breathing simultaneously from the primary second stage and the octopus. The Natural Convection Channel system and the metal design of the Abyss second stage achieves reliable performance even in cold water. A variety of pre-oriented pressure ports give you options for hose configurations even if you choose to use two independent regulators. 

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 
Mesh Grid: Patented design that reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents
Dynamic Flow Control (DFC) System: Minimizes the pressure drop that occurs in all regulator first stages when the diver inhales. The deeper the dive, the demand from airflow from the regulator rises. The DFC system operates in relation to the diver's actual air demand, independent of depth and tank pressure. It uses the Venturi Effect, optimizing the regulator's sensitivity and minimizing inhalation resistance, especially during dives in extreme conditions.
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.
The Tri Material Valve: Made of a central valve in nickel-plated brass; a highly-resistant polyurethane coating covering nearly the entire valve body to protect from wear and tear and an additional polyurethane covering to the surface (head) of the valve to provide a perfect seal, even under extreme conditions. Divers can breathe safely knowing uncontrollable free flow never occurs under any conditions.
Natural Convection Channel: Increases cold water performance by creating a flow of water across the regulator. The flow is driven by the change of density in water with temperature.
