An ideal travel companion, the compact MK11 balanced diaphragm first stage with DIN 300 connector combines with the C370 second stage to create a regulator system that's a great choice for dive travelers. Fully adjustable, the C370 includes an inhalation e?ort control knob along with a small coaxial dive/pre-dive lever for e?ortless air?ow at all depths. Other features include a rugged ?berglass-reinforced nylon cg, a large purge button that's easy to activate even when wearing thick gloves, and an exhaust tee that contributes to improved breathing. An ideal choice for dive travelers, female divers, and smaller-sized divers, the C370's compact size takes up little space in a dive bag. A good choice for divers who want the benefits of a sealed system for more temperate waters, the MK11 delivers constant and e?ortless air?ow una?ected by depth, tank pressure, or breathing rate. Made of chrome-plated brass, the MK11 first stage features two high pressure ports, two high-?ow LP ports, and two standard LP ports to maximize hose routing options. While an air-balanced diaphragm first stage has more moving parts than a piston first stage, its body is environmentally sealed to prevent water and pollutants from fouling the inner mechanism — making it perfect for diving in waters with suspended particles, silt, or contaminating materials. Backed by a manufacturer's limited lifetime warranty. Driven to constantly innovate and improve the diving experience, SCUBAPRO builds flawless equipment for the work, sport, and lifestyle of people whose passion is found below the surface.

External Intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily. Two high pressure, two low pressure and two high-flow LP ports maximize hose routing options. Marine grade brass body has sealed internal parts to prevent water and pollutants from fouling the inner mechanism while enhancing cold-water performance. Air-balanced diaphragm first stage design delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
