Mares MV Octopus

Octopus MV was created from the experience of the Mares laboratories, directly as a dedicated Octopus.

The MV Octopus is a lightweight, minimum dimensioned, and its characteristically compact shape, makes the MV easy to dive with. The special symmetrical shape means the Octopus is equally easy to use on the right or the left, for increased safety. The MV Octopus Second Stage with its 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 MV Octopus case is made from sturdy and durable techno-polymer material that has superior resistance to abrasion. The MV Octopus is a reliable, and simple downstream demand valve design.
