Aqualung Helix Pro Octopus

The Aqualung Helix Pro Octopus provides the same great performance as the Helix Pro primary second stage with its pneumatically balanced second stage that results in smooth, easy breathing. Thanks to its highly efficient heat exchanger, it is up to the rigors of cold-water diving. With its 39" (99cm) Hi-Viz yellow hose and front cover, it will be ready to provide life-sustaining air in an out-of-air situation. The easy-to-grip venturi lever prevents unwanted free flow at the surface while giving a performance boost at depth. A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. The Helix Octopus is compatible with EAN 40 new, out of the box. Equipped with a silicone mouthpiece with ergonomic bite wings. Octo weighs 7.3 oz (207g) without the hose and comes with an owner's manual.
