- The latest evolution of the Mares hero second stage
- The most compact high performance first stage
- The best possible performance from both stages
Abyss has long been a staple name in high performance, coupled now with elite small first stage MR42T: the best for a unique high calibre set up. The evolved design of Abyss second stage adds more metal on front cover and hose protector to achieve even further dependability in the most difficult diving conditions.

Patented technology, conceived and created to optimize performance, safety, and reliability. This brass valve is covered with a hard PU, and then the head is layered molecularly with a soft PU. Tri-material (brass, soft polyurethane, and ‚Äúheavy duty‚ÄĚ polyurethane) reaches a new level of durability.
ALL METAL TECHNOLOGY
Metal second stages have superior performance to 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 less dry mouth from breathing.
DFC - DYNAMIC FLOW CONTROL
The DFC system minimizes the intermediate pressure drop during inhalation, making it possible to use a simpler and more reliable second stage. No type of manual adjustment is 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 centre that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.
The patented mesh design of the second stage cover reduces the pressure of water flowing onto the second stage diaphragm and minimizes free-flow. Even in strong currents it eliminates the need for a knob to ‚Äėde-tune‚Äô your air delivery system to stop free flowing: Advanced technology through basic physics.
Mares developed the new ‚Äúsuperflex‚ÄĚ hose after many years of testing and research. The results achieved far surpass the tests required by EN250, and even the highly stringent additional tests Mares applies for use in extreme conditions. Its exceptional softness and extremely light weight guarantee the maximum freedom of movement.
