The CORE octopus provides the same great performance as the CORE primary second stage. Thanks to its highly efficient heat exchanger, it is up to the rigors of cold water diving. With its 39” hi-viz yellow hose and front cover, it will be ready to provide life-sustaining air in an out-of-air situation.

• The CORE octopus is pneumatically-balanced. This results in smooth, easy breathing
• The easy-to-grip venturi lever prevents unwanted freeflow 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
• Includes 39" yellow hose and yellow front cover
