This regulator system combines SCUBAPRO's premium diaphragm first stage with its newest air-balanced second stage.

The MK17 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. Its improved internal design allows more airflow from the LP ports which have been reconfigured for better hose routing.

Simple and reliable, the air balanced C370 delivers consistent airflow, ease of use and dependability, making it just the ticket for recreational divers in general, and dive travelers in particular.  Thanks to its compact size and lightweight, this is also a fantastic regulator for our female divers and smaller sized divers. With any of these regulator systems in your dive bag you'll be ready to hit the road.

It's a smart reg system for all kinds of diving applications.

First Stage

• Air-balanced diaphragm 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 low pressure ports maximize air delivery.
• High-flow performance is available from all four LP ports which are configured for optimum hose routing.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• Weight: INT 232: 860g; DIN 300: 640g
• Airflow at 200bar: (l/min): 242.
• Intermediate pressure: 9.0-9.8 bar

Second Stage

• Air-balanced valve for smooth inhalation effort at varying depths and supply pressures.
• Compact rugged fiberglass reinforced nylon casing and new exhaust tee take up little space in a dive bag.
• Stainless steel frame on the front cover adds the SCUBAPRO C-Series signature.
• The poppet and lever allows the design to maintain the same overall size as the C350.
• The exhaust tee is based on the S620 Ti's design and contributes to better work of breathing (a 10% improvement over the C350).
• User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA).
• Large purge button is easy to activate, even wearing thick gloves.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from smaller to largest.
• Weight: 171g.
• Airflow at 200bar: (l/min): 1600 bar
