Balanced sealed diaphragm first stage perfect for cold water diving, paired with a powerflow Downstream valve second stage, offering a reliable and an improved work of breathing compared to a classic downstream valve. With complete adjustment options.
The balanced diaphragm MK11, with its chrome-plated brass body specially designed to reduce size and weight, is an ideal travel companion. Its system features internal parts that are sealed from the elements, increasing reliability and performance.
The MK11's polished chrome forged brass body features identical high pressure and low pressure ports on each side so you can hook it up to your tank in either the up or down position while maintaining the same port layout. Also, two of the low pressure ports are high-flow, delivering about 15 percent more air than the standard low pressure ports. This means lots of effortless airflow with every breath.
The C370 is the most compact second stage in SCUBAPRO's line, so takes up little space when traveling. It is lightweight, breathes smooth and extremely easy, and offers a coaxial-flow inhalation effort control knob and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. The stainless steel front cover frame adds a bit of style.
