The Mares Ultra Adjustable Octopus Regulator is designed for use with the Mares Ultra Regulator Series (see SKU’s: MRSUA82X, MRSUA82XD, MRSU72X). Vortex Assist Design (V.A.D.) system: all Mares second stages offer the unique patented VAD system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low-pressure area in the center this keeps the diaphragm down during inhalation, giving very sensitive and easy breathing at all depths. The bypass has undergone a true transformation: 77% increase in flow cross section and double curvature to provide a smoother flow while optimizing performance. For the first time a Mares second stage regulator is equipped with a flow control (Twin Power), managing the delivery rate of gas from natural breathing to power breathing. By rotating the adjustment sleeve on the hose inlet, you can achieve VAD+ performance. Octopus is made of ultralight techno-polymer with a wide pivoting purge button.
