Lightweight, comfortable and without hampering your freedom of movement, the scuba regulator Air Control gives you an alternative air source while using the same hose for the octopus and the inflator. The pre-oriented mouthpiece makes it a suitable substitute to an octopus. The cover features the Mesh Grid system, made of soft material so the purge button is easy to push, even when wearing gloves. The mesh grid is designed to reduce the impact of water flow onto the second stage diaphragm—eliminating free flows even in strong currents. Complies with EC standards and with special adaptors that can be easily assembled on all BCDs. The ergonomic shape allows one-handed use.Ultralight Techno Polymer: Abrasion resistant and affordable material made for warm to moderate water temperaturesVortex Assisted Design (VAD) System: The air bypass tube sends air to the mouthpiesce 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.Mesh Grid: Patented design that reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currentsFluid Dynamic Deflector: Receives and properly directs the airflow from the bypass tube to the mouthpieceSuperflux Hose: Lightweight and soft for pliable movementSecond stage weight INT: 1/2lb.Two year limited warranty
