Enjoy the view around you even when you exhale with this regulator, which features a side exhaust that deflects air bubbles to prevent a crowded view. Its angled diaphragm combined with the Vortex Assisted Design (VAD) system ensures high performance. Features compensating openings in the back that minimize the chance of freeflows in strong current and easy purging. An over the shoulder hose configuration and a low profile breathing apparatus stay out of your way and give you room to move freely.  

Superflux Hose: Lightweight and soft for pliable movement
Ultralight Techno Polymer: Abrasion resistant and affordable, ideal for diving in warm and moderate water temperatures
Vortex Assisted Design (VAD) System: The air bypass tube sends air to the mouthpiece creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very easy breathing at all depths. In cold water diving, this system prevents ice crystals (which can be generated by the expansion of humid air in cold temperatures) from interfering with the proper operation of second stage components.
The Tri Material Valve: Made of a central valve in nickel-plated brass; a highly-resistant polyurethane coating covering nearly the entire valve body to protect from wear and tear and an additional polyurethane covering to the surface (head) of the valve to provide a perfect seal, even under extreme conditions. Divers can breathe safely knowing uncontrollable free flow never occurs under any conditions.
Dynamic Flow Control (DFC) System: Minimizes the pressure drop that occurs in all regulator first stages when the diver inhales. The deeper the dive, the demand from airflow from the regulator rises. The DFC system operates in relation to the diver's actual air demand, independent of depth and tank pressure. It uses the Venturi Effect, optimizing the regulator's sensitivity and minimizing inhalation resistance, especially during dives in extreme conditions.
