The Mares XR Vertical R2S VR Stage Regulator combines the first vertical second stage ever, combined with the extremely reliable R2S first stage. It is comfortable and easy to handle, perfect for the travel stage and decompression stage of your dives as well as for buddy breathing.
The Mares R2S First Stage Regulator 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 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. First stage R2S DIN has 4 LP ports with 3/8" UNF threads and 1 HP port with 7/16" UNF threads. Regulator is nitrox ready to 40% out of the box.
The Mares Second Stage Vertical Regulator (VR) is a mid-sized techno-polymer second stage regulator with its simple, yet reliable downstream demand valve design. The VR 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.
Regulator comes with a 3/8" threaded low pressure hose, weighs 622 g (23 oz) and comes with an owner's manual.
