This Aqualung Helix Pro Regulator Set Din is a mid-range regulator that is balanced on the first and second stages. It represents the DNA of the Aqualung regulators. It benefits from the patented ACD technology auto-closure device for sealing water out, Also ready for cold water diving, the integrated dry chamber keeps inner components clean and dry by isolating them from the outside environment.

Equipped with the unique Comfo-Bite mouthpiece and Lip shield included on the second stage, which is also removable, This feature-rich winner is the best value of any regulator on the market.

The first stage is fully protected even when the regulator is not under pressure, which means that the Aqualung Helix Pro can be serviced every two years due to the sealed environment in the first stage.
