Scubapro MK17 EVO/S600

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.

MK17 EVO First Stage

• 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 reinforced technopolymer design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.

A second stage regulator must translate natural breathing behaviour 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.
