ITEM #12.974.000

MK17 EVO/ S620Ti

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.

                        Second Stage

                        • 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.
                        • Weight: 179g.
                        • Airflow at 200bar: 1850 l/min.
