This reg system is full of features, offers SCUBAPRO reliability and is priced right. About 20 percent 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 full-featured S560 second stage, built with a rugged nylon fiberglass case, is lightweight too, and also easy to use. Together they create the must-have reg system for recreational divers of all skill levels.
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 increas- es 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 eas- ier mounting on a cylinder, and a redesigned cap protects internal components from water intrusion after the dive.
