Scubapro MK17 EVO / S600 Set

1st stage MK17 EVO DIN:

- 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.

2nd stage S600:

- Air balanced second stage valve smoothes out the inhalation effort at varying depths and supply pressures.

- Second stage’s rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is extremely durable.

- Metal valve housing (barrel) is able to withstand years of aggressive diving.

- User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.

- Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.

- Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
