Helix CPro octopus on a one-metre yellow hose
Aqualung supplies this set with a Helix CPro octopus, an alternate second stage, and its one-metre yellow hose, so you get the regulator and the octopus in one purchase.
Helix Pro Stage 3
The Helix Pro regulator and an octopus, fitted left or right as your training agency asks
Helix Pro Stage 3 is Aqualung's Helix Pro regulator, first and second stage, supplied with a Helix CPro octopus and its one-metre yellow 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. The regulator is the Helix Pro, the mid-range model in Aqualung's core range, balanced in both stages, with an Auto Closure Device (ACD) on the first stage and a braided hose that is easy to travel with. The full regulator detail is on our Aqualung Helix 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.
Choose a DIN or INT first stage
The first stage comes in two versions, DIN and INT (yoke), one per set: match the tank valves you dive with. Aqualung lists the first stage at 525 g in DIN and 740 g in INT, with a maximum working pressure of 300 bar in DIN and 232 bar in yoke.
Balanced in both stages, with ACD and a Venturi switch
The first stage is over-balanced and the second stage is pneumatically balanced, which Aqualung says gives superior breathing performance; Aqualung lists a work of breathing of 0.95 J/L. The first stage has Aqualung's patented Auto Closure Device (ACD) and a permanent dry chamber, and the second stage has a Venturi switch (MIN / MAX) and a heat exchanger.
Who it is for
Great for
- Divers who want the regulator and an octopus in one purchase: this set has both
- Divers whose training agency sets the side for the octopus and gauge: the octopus comes unassembled, to fit right or left
- Travelling divers: the braided hose is flexible and easy to transport
- 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 Pro regulator on its own; see our Aqualung Helix Pro page or ask us on LINE
- Advanced divers who want several fine adjustments to the breathing resistance: Aqualung says the Leg3nd Elite gives advanced divers independent micro-adjustments; ask us on LINE

FAQ
What is in the set?
One Helix Pro regulator, a DIN or INT first stage as you choose plus the second stage, and a Helix CPro octopus with its one-metre yellow 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 the first stage at 525 g (19 oz) in DIN and 740 g (26 oz) in INT (yoke), with a maximum working pressure of 300 bar in DIN and 232 bar in yoke. Not sure? Ask us on LINE.
How is it different from the Helix Pro regulator sold alone?
Aqualung's page for this set gives the same regulator description and figures as the Helix Pro page; the difference is that this set adds the Helix CPro octopus and its one-metre yellow hose. For the full regulator detail, such as the Comfo-Bite mouthpiece and the ports set in a T, see our Aqualung Helix Pro page.
How often does it need a service?
Aqualung says the regulator is serviced every 2 years for optimal performance. For questions about servicing, ask us on LINE.
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, but calls Helix Pro the mid-range regulator in its core range; the only second-stage control it lists is the Venturi switch, and the octopus can go on either side as your training agency requires. Just starting and not sure which set to pick? Ask us on LINE.
