Scubapro C350 Second Stage Regulator

The C350 is the most compact second stage in Scubapro's line. It is lightweight, breathes smooth and extremely easy, and offers an inhalation effort control knob and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. It is also the only second stage built with an Optimal Flow Design valve. This innovative design features a full-length poppet valve specially designed to optimize aerodynamic performance. This in turn allows air to flow unobstructed over the poppet valve surface, providing a smooth and controlled breathing experience that used to be reserved only for air balanced second stage designs.

Compact body and exhaust tee take up little space in a travel dive bag. Stainless steel frame on the front cover adds some style to the compact design. New poppet shape and size are effective at eliminating vibrations and whistles. Large purge button is easy to activate, even wearing thick gloves. Holes below the purge button increase water circulation on the diaphragm to improve sensitivity. Super-flow hose features an oversized bore that allows more air to flow on each inhalation. Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow. The second stage housing is manufactured using precision molded carbon fiber and techno-polymer. Regulator second stage comes with a 3/8" threaded hose and weighs 7.1 oz. (201 g).
