The MK25 balanced piston first stage is the absolute top performer, making this system the very best.

This newly polished chrome edition has 5 low pressure and 2 high pressure ports plus swivelling turret for convenient arrangement and personalisation of your gear. It includes anti-freeze protection for all diving temperatures and externally adjustable intermediate pressure for easy maintenance.

The classic downstream piston configuration is the simplest mechanism that exists to control the pressure drop from a tank to feed the second stage. The classic downstream valve is the first choice of diving centres and rental facilities worldwide for warm and moderate water temperatures.

To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 200bar INT version as well as 300bar DIN versions.

Classic downstream valves are particularly noted for their legendary safety and reliability. When in use, the downstream valve opens in the same direction as the incoming air flow. To close the valve and stop the air flow, a spring counteracts the force of the incoming air. Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve.

The Fixed VIVA (Venturi Initiated Vacuum Assist) flow vane is fixed in the pre-tuned ideal position for safe and uncomplicated use. It is extremely lightweight and compact making it comfortable for all divers, including novice divers newly initiated in the sport.

The SCUBAPRO uses a comfortable orthodontic mouthpiece on every second stage to reduce jaw fatigue and gum irritation. It was developed by dentists and dental laboratories and lasts longer than any other mouthpiece, because only a minimum effort is needed to hold it comfortably in place.
