A yellow hose that is quick to find
The 1 m hose and the front cover are yellow. Aqualung says the high-visibility yellow hose gives quick identification in an emergency.
Helix Pro Octopus
Performs like the Helix Pro second stage (per Aqualung), on a yellow hose
An octopus is a spare second stage on its own hose. If your buddy has an air emergency, they can breathe from it. Aqualung says the Helix Pro Octopus delivers the same high performance as the Helix Pro primary second stage. Its high-visibility yellow hose gives quick identification in an emergency. It is pneumatically balanced, with a Venturi switch you can work in gloves, a heat exchanger and a lip shield. Aqualung lists a work of breathing of 1.25 J/L. Designed and made in France.

Highlights
Cover channels against free-flow in strong current
Wide radial openings in the cover let water flow sideways over the diaphragm. Aqualung says they prevent free-flow when diving in strong currents and reduce cracking effort by 20%.
A Venturi switch you work in gloves
Set it to MIN for the least assistance and a higher inhalation effort, ideal to avoid free-flow. Set it to MAX for the most assistance and a lower inhalation effort. The overmolded lever works even in gloves.
Pneumatically balanced, with a heat exchanger
The Helix Pro Octopus is pneumatically balanced and has a heat exchanger. Aqualung marks it for cold and warm water and lists a work of breathing of 1.25 J/L.
Comfo-Bite mouthpiece and lip shield
The Comfo-Bite mouthpiece has a palate bridge and is made of hypoallergenic silicone. It swaps without tools and is held by a reusable clip, and there is a lip shield.
