I just bought the abyss 22 and already own the MR22T first stage that came with it, so im selling the new first stage. The whole setup is $479.99 on Diver Direct (click to view the page). It is NEW and has NEVER been used or even wet. Im selling it for $170.
"MR 22 diaphragm first stage featuring the DFC (Dynamic Flow Control) system and a replaceable HP seat connector. 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-plated and chromed brass. It is fitted with a preferential intermediate pressure port for connection to the main second stage, plus 3 other LP ports and 2 HP ports. The latter are inclined at a 45º angle to allow a more rational layout of hoses. and ergonomic exhaust tee ensures superior hydrodynamic performance and reduced exhalation resistance."
"The DFC system (Mares patented) minimizes the pressure drop that occurs in all regulator first stages when the diver inhales. This phenomenon is even more pronounced as depth increases and when airflow demand from the regulator rises.
The DFC system is an exclusive system, unique on the market, that operates in relation to the diver's actual air demand, independent of depth and tank pressure.
The DFC system uses the Venturi Effect, optimizing the regulator's sensitivity and minimizing inhalation resistance, especially during dives in extreme conditions."
"The Tri Material Valve is composed of:
A central valve body manufactured in nickel-plated brass;
A highly-resistant polyurethane coating covering nearly the entire valve body that can ensure elevated resistance to wear and mechanical stresses;
Finally, an additional covering is applied to the surface ("head") of the valve;
This covering is also polyurethane but has a softer "modulus" (hardness) to provide a perfect seal, even under extreme conditions.
Thanks to the use of a special technology ("adhesion at the molecular level") and the characteristics of the materials used, a high level of safety (uncontrollable free flow never occurs) and reliability is guaranteed under any conditions."
