MK25/A700 System
The MK25 teamed with Scubapro's exceptional new A700, offers superior ultra-high airflow system for maximum performance in all temperatures and diving conditions.  Scubapro is synonymous with piston-controlled first stages.  MK25 underscores this heritage with an array of proprietary features ensuring outstanding performance.  The MK25 balanced piston first stage is our absolute to performer, making this system our very best.

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.
