Key Features

    Coverplate design, which disperses the water flow around the 2nd stage diaphragm, reducing the likelihood of free-flow. The calibrated holes allow a large amount of water to flow through while simultaneously reducing undesirable dynamic effects, even when swimming against a strong current.
    Mares' first stages feature the exclusive DFC (Dynamic Flow Control) system, which minimizes the intermediate pressure drop during the inhalation phase, thereby considerably improving regulator performance in terms of breathing effort and inhalation resistance.
    The second stage body, molded from high strength technopolymers, is over molded with a special elastomer that gives a the Proton it unique look in addition to high abrasion resistance.
  • VAD
    - The unique Mares patented V.A.D. (Vortex Assisted Design) system. This system is unique and allows smooth breathing at all depths and its operating principle is very simple. The air coming from the hose passes through the second stage valve and is conveyed directly to the mouthpiece through the by-pass tube.
