What's in the box: 1st Stage, 2nd Stage and LP Hose

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 due to the incredibly fast moving air and thepressure 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

A second stage regulator must translate natural breathing behavior into mechanical reality A high quality second stage can significantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air The SCUBAPRO S-Series offers superior air flow characteristics and supreme performance The S555 second stage is the choice for passionate divers The S555 uses SCUBAPRO'S Air-balanced valve technology The air-balanced valve technology of SCUBAPRO's second stages features a balancing chamber in the second stage mechanism, slightly offsetting the force of the downstream air entering from the first stage This allows reduced spring tension and decreases the inhalation resistance to the lowest possible level The result is super smooth breathing in all conditions Venturi Initiated Vacuum Assist (VIVA) Another SCUBAPRO patented feature, the VIVA is available on the S555 second stage VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort A VIVA in MAX position gives powerful breathing support on every single breath; a VIVA in MIN position helps to prevent free flow on the surface, for training, for buddy breathing, in currents, or when used as an octopus Orthodontic mouthpiece SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place
