Brand new, never wet, never used, ScubaPro MK17 300 bar DIN. I bought a MK17/X650 set and only need the X650 so I am selling the MK17. This is an awesome 1st stage, I have two others that I use. Check out the pictures below...

MK17 FIRST STAGE
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.
The Diaphragm Technology. Diaphragm-based first stages are environmentally sealed so that water cannot enter the inner mechanism. Bearing in mind that regulators generate temperatures up to minus 30°C due to the incredibly fast moving air and the pressure drop involved, it is imperative that sensitive moving metal parts avoid contact with extremely cold water.
Therefore, diaphragm first stages have been the favoured choice of cold-water divers and those working in contaminated or muddy water.
SCUBAPRO diaphragm first stages feature balanced technology and are packed with patented features resulting in ultra fast flow to the second stage on demand and a fantastic overall performance.
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- The arrangement of high and low pressure hoses 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- Allows authorised SCUBAPRO service technicians to quickly fine tune or make adjustments after maintenance without the need to disassemble the first stage.
Cold Water Diving With SCUBAPRO:
Diving conditions can be drastically different, including extreme cold water and outside temperatures, posing the possibility of a regulator freezing. Therefore, resistance to freezing is imperative for the diver. All SCUBAPRO regulator systems are CE approved for 300bar cold water diving. Some models go even beyond this super stringent qualification and have successfully been tested in extreme cold diving conditions at less than 2°C.
As a specific anti-freezing measure, SCUBAPRO engineers have designed a patented finned cap for both the MK17 and the MK25 first stages for optimal cold water diving. The ribs act as a radiator to increase the surface area of heat transfer from the water to warm up the internal parts that have been drastically cooled down by the gas pressure drop.
On the MK17, a dry ambient pressure chamber enhances the resistance to real ice cold water at any depth compared to other dry chamber diaphragm first stages.
For cold water diving, SCUBAPROs second stages feature precision moulded carbon fiber and technopolymer valve housing and components. They even exceed the CE cold water norm. In addition, these components contribute to their lightweight features and corrosion resistance.
As with all SCUBA gear purchased from a non-authorized dealer, I recommend that you have this serviced prior to use.
