Bearing in mind that regulators generate temperatures as low as 22F (-5.5C) due to the incredibly fast-moving air and the pressure drop involved, it is imperative that sensitive moving metal parts avoid contact with extremely cold water or debris. Therefore, diaphragm first stages have been the favored choice of cold-water divers and those working in contaminated or muddy water. Scubapro diaphragm first stages feature balanced technology and are packed with patented features resulting in ultra-fast flow to the second stage on demand and a fantastic overall performance.

The Scubapro MK17 EVO 300 First Stage Din Regulator's streamline body is constructed of machined marine-grade chrome. The MK17 EVO has a balanced diaphragm to offer you peace of mind with its smooth breathing mechanisms and maximum performance that don't diminish as your tank's air pressure changes.

The Scubapro MK17 EVO 300 First Stage Din Regulator comes standard with the Thermal Insulating System (TIS), which keeps your first stage from freezing up and malfunctioning in cold water conditions. Additionally, its over-balanced diaphragm first stage design gives you better breathing performance at greater depths.

First stage regulator is equipped with two 7/16" threaded HP and four 3/8" threaded LP ports. Two of the LP ports are high flow ports (HFP) for easier breathing on demanding dives. The first stage weighs 22 oz. (625 g).
