Part: 416255DIN Item Includes1'st Stage - 2'nd Stage - Low Pressure Hose - Mares 2 Year Limited Warranty DescriptionThe Rover 2S regulator is an excellent choice for intensive rental use in the Diving Centers and for all divers who want reliability! The 2S first stage is the evolution of the piston regulator. The first stage is made of marine grade brass with a sandblasted finish for increase scratch resistance. The protection cover of the first stage is designed to allow the installation of an optional RFID chip for rental use managed by dedicated PC software. The lightweight compact and sturdy non-balanced first stage piston design with its Dynamic Flow Control (DFC) system minimizes the intermediate pressure drop during inhalation, making it possible to use a simpler and more reliable second stage regulator further increasing reliability. The DFC does not require any type of manual adjustment for the second stage due to the consistency of the stable air flow, even under extreme conditions. Regulator is nitrox ready out-of-the-box. The mid-sized techno-polymer second stage regulator with its simple, yet reliable downstream demand valve design has a Fluid Dynamic Deflector. This innovative deflector, developed after in-depth studies and tests of fluid dynamics, is engineered to receive, and properly direct the airflow from the bypass tube to the mouthpiece. Combined with the Vortex Assisted Design (VAD) system that creates a swirling vortex with a low-pressure area in the center of the regulator that keeps the diagram down during inhalation, for very sensitive and easy breathing at all depths. This simple and reliable design makes for easy and reduced maintenance. First stage has one high pressure port and four low pressure ports. Rover 2S has a 3/8" threaded 31.5" (80cm) hose and weighs 22 oz.
