The all Chrome Plated Marine Brass First Stage Regulator is a Balanced Diaphragm Design which transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism.
The Carbon 52X uses Tri-Material Valve Technology. This patented technology created to optimise performance, safety and reliability. The valve is covered with a hard Polyurethane (PU) and the sealing surface is a layered with a soft PU for a perfect seal. Tri-material (brass, soft PU and heavy-duty" PU) reaches new levels of durability.
The Carbon 52X Second Stage with its Vortex Assist Design (V.A.D.) system: all Mares second stages offer the unique patented VAD system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low pressure area in the center this keeps the diaphragm down during inhalation, giving very sensitive and easy breathing at all depths. The second stage cover features the new "mesh-grid" system for water inflow and outflow, which provides a further performance improvement.
