The S620 Ti embraces the best features of SCUBAPRO’s renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter but using the same-sized diaphragm, the S620 Ti delivers effortless airflow under all dive conditions (37% lower breathing effort than the S600). The S620 Ti is built tough: you’ll find a corrosion-free titanium barrel inside a rugged reinforced technopolymer case and front cover with a new, larger stainless steel frame reinforcement. The large purge button improves water circulation and the new exhaust tee enhances overall performance. This estimable second stage is equipped with full user adjustments. Accessory mouthpieces and hose protectors in matching colors let you coordinate with the rest of your dive rig.
