MK21/C370

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 design whose 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.

  • 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 optimizes 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.
  • Weight: INT 232: 780G; DIN 300; 570g.
  • Airflow at 200bar: (l/min): >7500.
