The Scubapro MK17 first stage is a cold water rated model with an environmentally sealed over balanced diaphragm design. Engineered for use in cold water, polluted or harsh environments, the MK17 provides excellent performance of up to 6500l/min of air flow even in the worst conditions.

The balanced diaphragm design allows the MK17 to provide reliable and consistent performance at any depth, cylinder pressure or condition. The environmental seal allows the first stage to adjust to the ambient pressure, maintaining performance without the need for water to act upon the internal parts directly which helps to prevent issues with ice building up.

A total of four low pressure and two high pressure ports allow easy regulator configuration and support for additional kit such as drysuit inflator hoses and wireless transmitters for dive computers.
