Built to deliver a steady supply of air in harsh diving conditions, when the going gets rough, the MK17 EVO/A700 gets going. The MK17 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. It is more compact than its predecessor, yet delivers better breathing performance. Its improved internal design allows more airflow from the LP ports which have been reconfigured for better hose routing. The A700 offers extraordinary breathing performance in a precision-handcrafted, full-metal package. Built for demanding divers and demanding conditions, with this reg system you can always be confident of your next breath. Ideal for cave and wreck diving too.
Air balanced diaphragm first stage, with its chrome-plated brass body, delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
Dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
Substantial increase in airflow (6900 l/min versus 6500 l/min) includes improved balance of air supply pressure.
Two high pressure and four high-flow ports maximize air delivery. High-flow performance is available from all four LP ports which are configured for optimum hose routing.
Air balanced second stage valve smoothes out the inhalation effort at varying depths and supply pressures.
Rugged full metal second stage case and valve housing (barrel) are able to withstand years of aggressive diving.
Metal second stage case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
Sectional exhaust tee and a first-rate purge help to deliver effortless inhalation and an ease of exhalation that is unmatched.
User controls include a diver-adjustable inhalation effort knob and coaxial Venturi-Initiated Vacuum Assist (VIVA) switch.
