For compact comfortable breathing performance in cold or silty water, the MK17 EVO 2/S620 Ti regulator system simply can’t be beat. The MK17 EVO 2 is more compact and lighter weight than its MK17 EVO predecessor and the MK19 EVO with a NEW forged body, dry chamber with a twin spring layout for increased reliability and compactness. The S620 Ti embraces the best features of SCUBAPRO’s renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter than the S600 but using the same-sized diaphragm, the S620 Ti delivers excellent performance providing effortless airflow under all dive conditions. The full titanium inlet tube is ultra- light, the large purge cover improves water circulation, and the exhaust tee increases performance while directing bubbles out of the field of view.
