About Scubapro Mark 17 Regulator DIN, First Stage Only

The Mk17 First Stage Regulator is the perfect choice for the recreational diver who wants the advantage of a diaphragm first stage for use in temperate waters. Diaphragm-based first stages are environmentally sealed so that water cannot enter the inner mechanism. The Mk 17 also incorporates a Dry ambient pressure chamber, providing better performance in cold water than any other diaphragm regulator. Bearing in mind that regulators generate temperatures as low as minus 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 MK17 first stage's streamline body is constructed of machined marine-grade chrome. The MK17 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. This first stage is available with a DIN or yoke configuration, making it ideal for divers around the globe. This first stage 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 HP and four LP Ports. Two of the LP Ports are High Flow Ports (HFP) for easier breathing on demanding dives. Regulator weighs 22 oz (625 g) and is covered by a limited lifetime warranty. Regulator does not include the Low Pressure Hose.

    Comments about Scubapro Mark 17 Regulator DIN, First Stage Only:

    I use this first stage on my usual diving regulator and liked it so much that I decided to get another for my pony bottle. I've got over 150 dives on the MK17 first stage and have never had a failure with it. It has performed flawlessly, is easy to breath and the IP stays locked without any creep. Since it is an environmentally sealed diaphragm, I don't have to worry about salt and crud getting inside and fouling things up. I typically test the IP and cracking pressure every six months or so and get it serviced every few years and it's good to go.

    A rock solid piece of gear.
