The new Scubapro MK17 EVO 300 First Stage Din Regulator is a premium high-performance balanced diaphragm first stage. This new version is more compact than its predecessor yet delivers better breathing performance.
Its improved internal design allows more airflow from the LP ports which have also been configured for optimum hose routing.Engineered specifically for cold water and harsh environments, its internal components are completely sealed off from the elements so neither water nor pollution can get inside the chrome-plated marine grade brass body to foul the mechanism, making it perfect for the PNW.
This total sealing system also allows for a dry ambient pressure chamber which works to prevent freezing, provides better protection and improves performance, ensuring trouble-free operation no matter how cold or murky the water gets.
Bearing in mind that regulators generate temperatures as low as 22°F (-5.5°C) 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).
Note: LP Hose Not Included
