MK17- 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 MK25 accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses. The MK17 and MK11
feature 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 authorized 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 4300psi 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 36°F. 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, SCUBAPRO’s second stages feature precision
molded 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.
