Description:

•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 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.
•The Optimal Flow Design valve (OFD) for reliable and high air flow, improving work of breathing compared to a downstream valve.
•Diver adjustable coaxial VIVA for powerful inhalation assistance and prevention of free flow.
•Diver adjustable inhalation control for personalized breathing effort.
•Redesigned mouthpiece tube allows better exhaust airflow.
