The Indestructible... Top performance and tough diaphragm technology for the first stage coupled with classic downstream valve design for the second stage: this is the essence of safety and reliability.


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 300bar first stage configurations.

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.

R395 SECOND STAGE REGULATOR

Classic downstream valve. 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.

Fixed VIVA (Venturi Initiated Vacuum Assist) flow vane. Fixed in the pre-tuned ideal position for safe and uncomplicated use.

Extremely lightweight and compact. Comfortable for all divers, including junior divers newly initiated in the sport.

Orthodontic mouthpiece. 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.
