Helix Compact Pro octopus on a one-metre hose
Aqualung supplies this set with a Helix Compact Pro octopus, an alternate second stage, and its one-metre hose, so you get the regulator and the octopus in one purchase.
Helix Compact Pro Stage 3
The travel-ready Helix Compact Pro and its octopus, in one set
Helix Compact Pro Stage 3 is Aqualung's Helix Compact Pro regulator, first and second stage, supplied with a Helix Compact Pro octopus and its one-metre hose, so you get both in one purchase. The octopus is delivered unassembled, so the octopus and the pressure gauge can be installed on the right or the left, as your training agency requires. You choose the first stage: DIN or INT, one per set. Aqualung calls the Helix Compact Pro the smallest and most compact regulator it has ever produced, made for divers who travel often and pack light, with a compact second stage that Aqualung calls ideal for smaller faces. The full regulator detail is on our Aqualung Helix Compact Pro page. Designed and made in France.

Highlights
Delivered unassembled, to fit left or right
Aqualung delivers the octopus unassembled, so the octopus and the pressure gauge can be installed on the right or the left, as your training agency requires. Not sure which side yours asks for? Check with your instructor or ask us on LINE.
The regulator Aqualung calls its smallest ever
Aqualung calls the Helix Compact Pro the smallest and most compact regulator it has ever produced. The over-balanced first stage is travel-ready, with an Auto Closure Device (ACD) and a permanent dry chamber, and Aqualung designed the model equally for warm and cold water.
A compact second stage with two breathing adjustments
Aqualung says the compact second stage is ideal for smaller faces, such as those of women and younger divers. You tune your breathing with a Venturi switch (MIN / MAX) that works in gloves and a cracking-effort adjustment. Aqualung lists a work of breathing of 1.35 J/L.
Who it is for
Great for
- Divers who want the regulator and an octopus in one purchase: this set has both
- Divers who travel often and pack light: Aqualung made the Helix Compact Pro for jetsetters and minimalists
- Divers with smaller faces, such as women and younger divers: Aqualung calls the compact second stage ideal for them
- Divers whose training agency sets the side for the octopus and gauge: the octopus comes unassembled, to fit right or left
- Nitrox divers: Aqualung rates the regulator up to 40% O₂ when new, out of the box (21% in Europe)
Maybe not for
- Divers who already own an octopus: Aqualung also sells the Helix Compact Pro regulator on its own; see our Aqualung Helix Compact Pro page or ask us on LINE
- Divers who prefer a full-size second stage: Aqualung built this one compact, for smaller faces. Not sure which size suits you? Ask us on LINE

FAQ
What is in the set?
One Helix Compact Pro regulator, a DIN or INT first stage as you choose plus the second stage, and a Helix Compact Pro octopus with its one-metre hose. Aqualung does not list a pressure gauge in the set. Need one too? Ask us on LINE.
Why does the octopus come unassembled?
Aqualung delivers it that way so the octopus and the pressure gauge can be installed on the right or the left, as your training agency requires. Not sure which side yours asks for? Check with your instructor or ask us on LINE.
DIN or INT: which one should I choose?
It is how the first stage connects to the tank valve, so match the valves you dive with; each set comes with one. Aqualung lists a maximum working pressure of 300 bar in DIN and 232 bar in yoke. Aqualung's set page and regulator page give different first-stage weights, so we leave them out for now. Need the weight, or not sure which to choose? Ask us on LINE.
How is it different from the Helix Compact Pro regulator sold alone?
Aqualung's page for this set gives the same regulator description as the Helix Compact Pro page; the difference is that this set adds the Helix Compact Pro octopus and its one-metre hose. For the full regulator detail, such as the Comfo-Bite mouthpiece and the braided hose, see our Aqualung Helix Compact Pro page.
Can I use it with nitrox?
Aqualung lists the regulator as compatible up to 40% O₂ when new, out of the box (21% in Europe). Planning to dive nitrox? Ask us first.
Is it OK for beginners?
Aqualung does not name a skill level. The second stage has two controls, the Venturi switch and the cracking-effort adjustment, and the octopus can go on either side as your training agency requires. Just starting and not sure how to set them, or which set to pick? Ask us on LINE.
