The Scubapro C370 Regulator – 2nd Stage Only evolves from the popular C350 with a balanced valve and a brand-new exhaust tee inspired by the S620 Ti design. It delivers a 10% improvement in work of breathing and adds a compact hi-flow mouthpiece for enhanced airflow and comfort during scuba diving and underwater exploration.

Built for durability in demanding environments, the second stage combines precision-molded fiberglass-reinforced nylon with a stainless steel cover frame. The diver-adjustable inhalation effort provides personalized breathing control, while the Linear Air-Balancing Valve and compact body with an exhaust tee help maintain smooth, efficient airflow across your diving gear sessions. Lightweight and portable, it fits neatly into your travel dive bag without compromising performance.

Designed to prevent free flow in challenging conditions, this regulator features Venturi Initiated Vacuum Assist (VIVA) with a dive/pre-dive control switch, a large purge button for thick gloves, and a compact orthodontic mouthpiece that fits all mouth sizes. The 3/8" LP hose and streamlined design contribute to a reliable, efficient underwater breathing experience in various water temperatures and environments.
