Second Stage.  Abyss' second stage, with its V.A.D. system, is made of nickel- and chrome-plated brass.  This material offers a number of benefits, i.e.: absolute ruggedness, thinner walls, hence compact dimensions obtained without using smaller-diameter diaphragms; this results unreduced water drag; anti-freeze function, which is enhanced by the "radiator action" of the metal. Its streamlined shape optimizes the traditional profile that is now made precious by the functional reliefs on the cover which were developed to make water inflow and outflow easier while breathing and swimming. The large manual purge button is placed in a central, perfectly ergonomic position. The mouthpiece is of soft hypoallergenic silicone; no distress and no fatigue, even after very long dives.

Technological perfection coupled with a perfectmaterial: Titanium. Abyss MR 22 Titanium is the "flagship" regulator of MARES range. Prestige and added performance. The precious Titanium coating is provided to protect all metal parts of the first and second stages and is obtained through PVD (Physical Vapor Deposition) to guarantee a unique shining look and ultimate abrasion and corrision resistance.
