The Aqua Lung CORE octopus provides the same great performance as the CORE primary second stage.
- The CORE octopus is pneumatically-balanced, resulting results in smooth, easy breathing
- 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
- Includes 39″ yellow hose and yellow front cover
