The revolutionary design of this second stage introduces a multiplicity of benefits when combined with Mares' high performing 52 first stage and encased in a fasionable white cover. The Instinct 52 Regulator's side exhaust deflects the exhaled breath so that hardly any bubbles will ever crowd your view. The angled diaphragm combined with the VAD system ensures high performance in any orientation. In addition, the regulator's compensating openings in the back minimize the likelihood of freeflows in strong current while the internal conic shape allows for easy water clearing in all positions. The optimized angle of the hose allows for easier movement. Divers will experience less jaw fatigue thanks to the center of gravity of the mouthpiece being closer to the mouth.
Dynamic Flow Control (DFC) System: Minimizes the pressure drop that occurs in all regulator first stages when the diver inhales. The deeper the dive, the demand from airflow from the regulator rises. The DFC system operates in relation to the diver's actual air demand, independent of depth and tank pressure. It uses the Venturi Effect, optimizing the regulator's sensitivity and minimizing inhalation resistance, especially during dives in extreme conditions.
Superflux Hose: Lightweight and soft for pliable movement
The Tri Material Valve: Made of a central valve in nickel-plated brass; a highly-resistant polyurethane coating covering nearly the entire valve body to protect from wear and tear and an additional polyurethane covering to the surface (head) of the valve to provide a perfect seal, even under extreme conditions. Divers can breathe safely knowing uncontrollable free flow never occurs under any conditions.
Ultralight Techno Polymer: Abrasion resistant and affordable, ideal for diving in warm and moderate water temperatures
Vortex Assisted Design (VAD) System: The air bypass tube sends air to the mouthpiesce creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very easy breathing at all depths. In cold water diving, this system prevents ice crystals (which can be generated by the expansion of humid air in cold temperatures) from interfering with the proper operation of second stage components.
