This reg system is feature-rich which offers SCUBAPRO reliability and is priced right. 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 full-featured S560 second stage, built with a rugged reinforced techno-polymer case, is lightweight too, and also easy to use. Together they create the must-have reg system for recreational divers of all skill levels.
Technical Information First Stage
Air balanced diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
The environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
The dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
Improved airflow on all LP ports
External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
Available in either 232bar INT or 300bar DIN configurations.DIN version comes with a dual-compound wheel that features an ergo shape and soft grip on a rugged black nylon frame.
Airflow at 200bar: 6900 l/min.
Intermediate pressure (bar): 9.0-9.8.
Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
Rugged reinforced technopolymer case and front cover are able to withstand years of aggressive diving.
Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
Uses the S600’s large-diaphragm inside a compact casing for maximum breathing sensitivity.
Metal case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
User controls include an easy-grip diver-adjustable in-halation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever.
Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
The ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
