Whats in the box:Second Stage Octopus with LP Hose
Protons second stage is made of nickel and chrome-plated brass. These materials offer a number of benefits: ruggedness and thinner walls which allow compact dimensions obtained without using smaller-diameter diaphragms; this result in reduced water drag. The second stage ha an anti-freeze function, which is enhanced by the "radiator action" of the metal.
All Mares second stages are a reliable downstream valve design and offer the unique patented Vortex Assisted Design (VAD) system. The air bypass tube conveys 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 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. The patented mesh design of the second stage cover reduces the pressure of water flowing onto the regulators diaphragm and minimizes free-flow. Even in a strong current it eliminates the need for a knob to de-tune your air delivery system- advance technology through basic physics.
Furthermore, the compact and ergonomic exhaust tee ensures superior hydrodynamic performance and reduced exhalation resistance. The mouthpiece is made of soft hypoallergenic silicone: limiting jaw fatigue and offering a secure fit even after very long dives. The Proton Metal Octopus comes with a limited lifetime warranty.
