This package pairs the Aqualung Helix Compact Pro regulator with the Helix Pro Octopus as a matched backup, so your primary and alternate air source share the same balanced design, heat exchangers, and Comfo-Bite mouthpiece feel. The Helix Compact Pro trims the size and weight of the standard Helix Pro first stage while keeping its balanced diaphragm design and sealed internals, and its second stage adds a venturi control and heat exchangers to resist icing in cold water. At checkout you can choose which regulator anchors the package: Aqualung Helix Compact Pro, Aqualung Helix Pro, or Aqualung LEG3ND.
The Helix Pro Octopus is built on the same Helix Pro second stage as the primary, so a donated regulator breathes the way your buddy already expects. It carries its own heat exchangers to fight cold-water icing, an in-line venturi knob sized for use with gloves, and a high-visibility yellow hose and front cover so it’s easy to find in an emergency.
Both regulators use standard Aqualung parts, which keeps servicing straightforward at your local dive shop. Together they give you a travel-friendly primary and a dependable backup that behave the same underwater, from breathing resistance to mouthpiece comfort.
