The new Rover 2 is an excellent choice for intensive rental use in the Diving Centers and for all divers who want reliability! The new R2 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, plus easy and reduced maintenance for INT and DIN version.The Rover 2 has a simple non-balanced piston first stage design that is great for the entry level diver or to be used in rental programs. The exclusive MARES DFC system featured minimizes the intermediate pressure drop which occurs in all regulators during the inhalation phase. This pressure drop is greater when higher airflow is demanded of the regulator. The DFC system substantially reduces breathing effort and inhalation resistance, especially during deep dives and under high air flow conditions.The second stage Vortex Assist Design (V.A.D.) system: 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 the center this keeps the diaphragm down during inhalation, giving very sensitive and easy breathing at all depths. Mares Rover second stage incorporates the Fluid Dynamic Deflector, developed after in-depth studies and tests of fluid dynamics, is engineered to receive and properly direct the airflow from the bypas s tu
