The Helix octopus provides the same great performance as the Helix Pro primary second stage.

The Helix octopus is pneumatically balanced resulting in smooth and easy breathing
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 easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth
Includes 1m yellow hose and yellow front cover making it easy to locate in an emergency
