The C370 is a high perfomance second stage. Based on the compact C350, the C370 brings forth the best features of its predecessor while adding a balanced valve to its design. A brand new exhaust tee, based on the S620Ti, contributes to an improved work of breathing. A compact hi-flow mouthpiece, also borrowed from the S620Ti, has been added to increase both airflow and comfort. Fully adjustable, the C370 includes a user-adjustable inhalation effort control knob along with small coaxial dive/predive lever. The compact C370 is lightweight, breathes easy and offers full user control to deliver effortless airflow.
