Rover 12S Regulator


Model # 15666910 | Mfg # 416166INT
In stock online.

State-of-the-art technology to ensure easy, natural breathing sums up this first stage regulator with a balanced diaphragm. It uses the Mares Tri-material valve with four, LP ports for optimum hose placement. This midsize second stage features a cover made of soft material that makes pushing the over-sized purge button simple, even while wearing dive gloves. Mounts on Scuba Tank using Yoke unit.

Ultralight Techno Polymer: Abrasion resistant and affordable, ideal for diving in warm and moderate water temperatures
Vortex Assisted Design (VAD) System: The air bypass tube sends 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 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.
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.
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.
Fluid Dynamic Deflector: Receives and properly directs the airflow from the bypass tube to the mouthpiece 
Mesh Grid: Patented design that reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents
