Designed to be the ultimate first stage for cold water or contaminated diving conditions.

Its design makes it substantially smaller and lighter than the original MK19.

Air-balanced diaphragm delivers consistent and effortless airflow, regardless of depth,
tank pressure, or breathing rate.

Environmentally sealed system prevents water and pollutants from fouling the inner
mechanism.

Its dry chamber is equipped with a double spring, making it more compact and reliable.

Two opposing high-pressure ports allow the first stage to be positioned either up or down,
plus provide for an optimum hose/transmitter layout.

Swivel turret comes with four High-Flow LP ports plus one axial Super High-Flow LP port
to maximise hose routing options.

Compact size, light weight and superb breathing performance continue in the best
SCUBAPRO regulator tradition.

Ideal first stage for recreational, technical, professional and military divers.
