The C370 brings forth the best features of its predecessor, the C350, while adding a balanced valve to its design. Its new exhaust tee, based on the S620 Ti’s design, contributes to a 10% improvement in work of breathing over the C350.

• Air-balanced second stage valve smoothes out the inhalation effort at varying depths and supply pressures.
• Compact second stage fiberglass reinforced nylon casing with new exhaust tee takes up little space in a dive bag.
• User controls include a diver-adjustable inhalation effort knob and coaxial dive/pre-dive lever.
• Large purge button is easy to activate, even wearing thick gloves.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes.
