Mares Abyss 22 Regulator - 1st Stage + 2nd Stage + Superflex Hose: 

The regulator that has broken every record now has a new Front cover with metal insert and a Mesh-Grid for better heat exchange. Abyss gained its reputation for reliability by setting many diving records , such as deep solo dive at 313m and 101 divers breathing simultaneously for 40 min from a single MR22 first stage. Firm tradition has evolved thanks to the new engineering and design. All Metal, more performance, more reliability-more Abyss.

FOR DEMANDING DIVERS - Those who dive frequently and in difficult conditions need products featuring superior quality and consistent performance, time and time again. Mares has always focused on new technologies and innovative products that lead to concrete benefits: superior reliability and performance will be appreciated by the most experienced demanding divers.

MAX COMFORT - Comfort is always one of the primary design elements in Mares equipment. Mares through superior technology continues to research, innovate and upgrade your level of comfort before and during your dive. Equipment marked with Max Comfort bring this quality of comfort to the most up-to-date premier pinnacle. TRI-MATERIAL VALVE - 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.
