Scubapro MK17 EVO/G260 SET

1st 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.
• Patented XTIS (Extended Thermal Insulating System) insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
• Two high-pressure and four high-flow low-pressure ports maximize air delivery.
• High-flow performance is available from all four LP ports which are configured for optimum hose routing.
• Precision-moulded, lightweight components and anti-freeze materials provide high corrosion resistance and enhance cold water performance.

2nd Stage

• A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
• High-flow exhaust valve that reduces exhalation effort for better breathing comfort.
