Description:Light weight, sturdy and compact first stage
The scuba regulator Rover 2S is an excellent choice for intensive rental use in the Diving Centers and for all divers who want reliability.
The new R2S first stage is the evolution of the piston regulator. A sandblasted finish to increase scratch resistance. The protection cover is designed to allow the installation of an RFID chip for rental use managed by dedicated PC software.
Easy and reduced maintenance for INT and DIN version.
Mid-size second stage
Ideal for Diving Centers
Mares Regulators Technologies:
DFC: 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.
TRI-VALVE MATERIAL: 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 SYSTEM: 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.
