The MK11/C350 is a great choice for dive-trekkers. 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. The C350 is the most compact second stage in SCUBAPRO's line, so takes up little space in a travel bag. It breathes smooth and easy, and offers an inhalation effort control knob and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. With this system in your dive bag you'll be ready to hit the road.
