This complete regulator set pairs the Aqualung Helix Pro as your primary first and second stage with a Helix Stage 3 Black regulator and matching octopus for backup air, plus a two-gauge console to keep pressure and depth readings in one place on the hose. Choose DIN or YOKE at checkout to match your cylinder valve.
The Helix Pro uses a balanced diaphragm first stage that’s sealed against water and particulates, a helpful trait in cold or silty conditions. Four medium-pressure ports are arranged in a T orientation so hoses route cleanly to the second stage, octopus, inflator, and drysuit without crowding, alongside two high-pressure ports. The second stage is pneumatically balanced and uses heat exchangers to resist icing, paired with a Comfo-Bite mouthpiece and a glove-friendly venturi knob. It’s compatible with EAN 40 right out of the box.
The Helix Stage 3 Black shares the same balanced diaphragm design and Comfo-Bite mouthpiece, so your octopus performs like your primary regulator when you need it. The two-gauge console rounds out the set with a submersible pressure gauge reading to 5,000 psi/350 bar on a Swiss-made shock-resistant Bourdon tube, a luminescent face with an integrated temperature scale, a one-way safety valve, and a 36-inch hose, and it’s rated for nitrox mixes up to 50%.
