The ultra-compact MK21/C370 regulator system delivers the ideal blend of comfort and performance. About 20% smaller than SCUBAPRO’s flagship MK25 but benefitting from the same core technology, the MK21 features a modern, cutting-edge designwhose size and weight make it an excellent choice for travel divers. The C370 brings forth the best features of its predecessor, the C350, while adding a balanced valve to its design. Its exhaust tee, based on the S620 Ti’s design, contributes to a 10%improvement in work of breathing over the C350. Together they create a no-nonsense air delivery system that delivers big performance in a small package.
First Stage: Air-balanced flow-through piston provides constant and effortless airflow unaffected by depth, tank pressure or breathing rate.
Polished chrome-plated marine grade brass body is close to 20% smaller than the MK25, making it an easy travel companion.
Unique thermal exchange design with external fins optimises freezing resistance.
Two high pressure ports, one on each side of the body, allow the first stage to be positioned either up or down.
Standard “smart” hose routing cap offers four low pressure ports angled for more convenient hose routing (+/- 20º).
Optional hose routing cap increases routing configurations with four angled low pressure ports (0°/30°) plus a fifth centralized high-flow low pressure port, ideal for technical diving.
Redesigned yoke allows for easier mounting on a cylinder, and a redesigned cap protects components from water intrusion after the dive.
