New-evolution diaphragm first stage and premium all-metal second stage create a powerful air delivery system.
Built to deliver a steady supply of air in harsh diving conditions, when the going gets tough, the MK17 EVO/A700 gets going.
The new MK17 EVO is SCUBAPRO's premium high performance balanced diaphragm first stage. 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. 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. 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.
The A700 second stage, with its hand-crafted all-metal casing, screw-down casing cover, metal valve housing and over-molded accents, exhibits a real muscularity in design. Its air-balanced valve technology and oversized exhaust valve work in conjunction with a well designed sectional exhaust tee, a first-rate purge and responsive user controls to create a bullet-proof breather with effortless inhalation and an ease of exhalation that is unmatched.
Built for demanding divers and demanding conditions, the MK17 A700 is the first stage of choice for harsh environments and cold-water conditions, and ideal for cave and wreck diving. Designed to deliver a smooth and steady supply of air no matter how frigid or murky the water gets, with this reg system you can always be confident of your next breath.
