The Aqua Lung Helix Compact Pro Octopus is the alternate air source built to match the Helix Compact Pro regulator, using the same reduced-size second-stage housing, a pneumatically balanced valve and a patented heat exchanger, and it ships with a 1 m yellow hose and a high-visibility yellow front cover so a buddy can find it fast. It is a dedicated backup second stage for divers who want a smaller, lighter octopus clipped to the BCD.
Who it is for
This octopus suits divers assembling or updating a Helix Compact Pro system, and anyone who wants their backup second stage to take up less room clipped into the BCD triangle. The compact housing trims bulk and weight from the overall setup, which travelers and divers who dislike a dangling octopus tend to appreciate. The heat exchanger and in-line venturi lever also make it a sensible choice for colder water and for divers who want the octopus held closed against unwanted free flow while it hangs unused.
Key details
- Second stage: pneumatically balanced, balanced downstream valve, for smooth and easy breathing.
- Heat exchangers: patented design surrounding the valve mechanism, dissipating the cold of gas expansion while drawing in ambient water warmth.
- Venturi: in-line venturi lever prevents unwanted free flow at the surface and adds a performance boost at depth.
- Visibility: high-visibility yellow front cover and 1 m yellow hose.
- Mouthpiece: Comfo-Bite, which stays seated without jaw effort.
- Controls: venturi vane yes, inhalation adjustment knob no, lip shield no.
