The Aqualung Helix Pro Octopus provides the same great performance as the Helix Pro primary second stage by featuring a pneumatically balanced design that results in smooth, easy breathing. You’ll greatly appreciate its highly efficient heat exchanger which surrounds the valve mechanism, dissipating the cold caused by gas expansion while drawing in the warmth of the ambient water. Your dive buddy will be thrilled to know you are prepared to help them in the event of an emergency situation. With its 39" (99cm) Hi-Viz yellow hose and front cover, you will be ready to breathe life-sustaining air in an out-of-air situation. The Hi-Viz yellow hose allows you and your dive buddy to quickly recognize your octo in case of an emergency. The Helix Pro Octo is compatible with EAN 40 new, out of the box. And once you dive underwater, you can be sure you’ll breathe comfortably with a silicone mouthpiece with ergonomic bite wings. For over 75 years, Aqualung has been a pioneer in designing revolutionary dive and snorkel gear to fit your needs and provide you with the best possible diving experience.
