- 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.
