Mares Prestige 12S Regulator
Performance and reliability in a new compact and light first stage!
Prestige 12S, the regulator you want! More compact and even lighter, it achieves maximum compactness in the new DIN version.
The four low-pressure ports are pre-oriented and allow for optimum arrangement of the hoses, which are now even softer and lighter.
A medium-size second stage offers easy, natural, regular breathing.
DFC - Dynamic Flow Control
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.
VAD Ststem - Vortex Assisted Design
The air coming from the LP-hose passes through the second stage control valve and is conveyed directly to the mouthpiece through the by-pass tube (Mares patented). In the mouthpiece connector, the airflow creates a swirling action, or “vortex”. The core of the vortex is a low-pressure area, which, during inhalation, helps to hold down the second stage diaphragm, thus markedly increasing regulator sensitivity. The decisive advantage of the VAD System lies in the precision of its control. The VAD supplies the inhalation effort with just the intensity required.
Another advantage of the VAD system is related to the bypass tube, through which most of the air is delivered. 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.
Mesh Grid 2nd Stage
Patented design which reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents.
