The Proton (V42) diaphragm first stage features the DFC system and a replaceable HP seat connector The exclusive MARES DFC system featured minimizes the intermediate pressure drop which occurs in all regulators during the inhalation phase This pressure drop is greater when higher airflow is demanded of the regulator The DFC system substantially reduces breathing effort and inhalation resistance, especially during deep dives and under high air flow conditions The high pressure poppet was designed for a "2 year or 200 dives" service interval; double the high pressure seat life standard!
Compact body, in a modern and smart style, it is made of hot-forged nickel-plating and chromed brass It is fitted with a preferential intermediate pressure port for connection to the primary second stage, plus 3 other LP ports and 2 HP ports with 7/16" UNF thread The latter are inclined at a 45° angle to allow a more ergonomic layout of hoses
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
The Proton 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
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 V42 Proton has a hose is 3/8" Threaded hose and is 29 5" (75 cm) in length Mares V42 Proton Metal comes with a limited lifetime warranty
