Mares Proton 42 Metal She Dives Regulator

Patented technology, conceived and created to optimize performance, safety, and reliability. This brass valve is covered with a hard PU then the head is layered olecularly with a soft PU. Tri-material (brass, soft polyurethane, and “heavy duty” polyurethane) reaches a new level of durability.

 ALL METAL TECHNOLOGY

Metal second stages have superior performance than plastic second stages, especially in cold water, thanks to the high thermal conductivity that limits the freezing effect. Additional benefits are the improved durability, the longer working life and the less dry mouth breathing.

 DFC - DYNAMIC FLOW CONTROL

DFC system minimizes the intermediate pressure drop during inhalation, making it possible to use a simpler and more reliable second stage. Any type of manual adjustment is not necessary, thanks to the consistency derived from first stages that guarantees a stable flow of air, even under extreme conditions.

 VAD - VORTEX ASSISTED DESIGN

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 center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.

 MESH-GRID

The patented mesh design of the second stage cover reduces the pressure of water fl owing onto the second stage diaphragm and minimizes free-flow. Even in strong currents it eliminates the need for a knob to ‘de-tune’ your air delivery system to stop free fl owing: Advanced Technology through basic physics.

SUPERFLEX HOSE

Mares developed the new “superflex” hose after many years of testing and research. The results achieved far surpass the tests required by EN250, and even the highly stringent additional tests Mares applies for use in extreme conditions. Its exceptional softness and extremely light weight guarantee the maximum freedom of movement.
