Mares Regulator Rover 2S


Mares Regulator Rover 2S

Rover S2S is an excellent choice for intensive use at a Diving Center and for recreational divers who demand reliability. The medium-size second stage features a cover made of soft material that makes it easy to push the purge button, even when wearing gloves. The latest technologies offer easy, natural, regular breathing.

Mares 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 divers actual air demand, independent of depth and tank pressure.
The DFC system uses the Venturi Effect, optimizing the regulators sensitivity and minimizing inhalation resistance, especially during dives in extreme 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.
