Scubapro MK17 EVO/S620 Ti

The new S620 Ti embraces the best features of SCUBAPRO's renowned S600 in an upgraded, state-of-the-art design. Delivering excellent performance; the S620 Ti's work of breathing has been reduced by 37% over the S600, providing effortless airflow under all dive conditions. The large purge button improves water circulation, and the new exhaust tee directs bubbles out of the field of view.  It's a stellar combination can be relied upon to deliver top-line performance in all dive conditions.

MK17 EVO First Stage

• Air balanced diaphragm first stage, with its chrome-plated brass body, delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
• Dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
• Substantial increase in airflow (6900 l/min versus 6500 l/min) includes improved balance of air supply pressure.
• Two high pressure and four high-flow ports maximize air delivery. High-flow performance is available from all four LP ports which are configured for optimum hose routing.
• Air balanced second stage valve smoothes out the inhalation effort at varying depths and supply pressures.
• Rugged reinforced technopolymer design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.

S620 Ti 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.
• User controls include an easy-grip diver-adjustable inhalation 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.
• Ultra-comfortable compact orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
• Airflow at 2900psi/200bar: 1850 l/min.
