The MK11/C370 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 C370 brings forth the best features of its predecessor, the C350 while adding a balanced valve to its design. Its exhaust tee, based on the S620 Ti’s design, contributes to a 10% improvement in work of breathing over the C350. With this reg system in your dive bag, you’ll be ready to hit the road.
