A high performance balanced diaphragm first stage regulator, the MK17 has been engineered for harsh environments and for use in ice cold water or polluted environments. Resistance to cold has indeed been a key element in the engineering of the MK17.


  • Dry ambient pressure chamber, providing better performance in cold water than any other diaphragm regulator. The diaphragm design prevents the entry of water into the first stage mechanism and enhances a trouble-free operation, even in the coldest conditions.
  • Patented finned cap with ribs increase surface area to maximise heat transfer from the water to warm the cold internal components.

  • The balanced technology provides consistent performance at all cylinder pressures, at any depth and optimises the second stage performance, thus allowing for effortless breathing.

  • Two opposite high pressure ports for arrangement of high and low pressure hoses which is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck.

  • Multiple low pressure ports for ultimate freedom in the arrangement of low pressure hoses,  the MK17 features four stationary low pressure ports, two of them HF.  High flow ports deliver about 15% more air than conventional ports.

  • DIN/INT first stage configurations- To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 200bar INT version as well as 300bar DIN versions.

  • Externally adjustable intermediate pressure alows authorised SCUBAPRO service technicians to quickly fine tune or make adjustments after maintenance without the need to disassemble the first stage.
