MK17/C300 regulator combines the new OFD technology with the sturdiness of our balanced diaphragm first stage.
The Optimal Flow Design valve (OFD) for reliable & high air flow, improving work of breathing compared to a downstream valve.
Diver-adjustable coaxial VIVA for powerful inhalation assistance & prevention of free-flow.
Diver adjustable inhalation control for personalized breathing effort.
Redesigned mouthpiece tube allows better exhaust air flow.
Available with either 232bar INT or 300bar DIN fi rst stages.
Our MK17/C300 regulator combines the new OFD technology with the sturdiness of our balanced diaphragm first stage.
Engineered for use in cold water, polluted or harsh environments.
Consistent performance at all tank pressures at any depth.
The dry ambient pressure chamber provides better protection & performance.
The balanced diaphragm, prevents entry of water into the first stage mechanism.
Scubapro MK17 First Stage
A high performance balanced diaphragm first stage regulator, the MK17 has been engineered for harsh environments & for use in ice cold water or polluted environments. Resistance to cold has indeed been a key element in the engineering of the MK17.
