Aqualung Helix Pro regulator with Octopus
Compact, reliable and powerful, these are the key features of the mid-range Aqualung Helix regulator, which the manufacturer claims is the DNA of Aqualung Regulators.
This popular regulator is also available in our online dive shop as a Helix Pro complete regulator system with the Helix regulator together with an accurate finimeter, a high quality inflator hose and an Aqualung regulator bag.
Aqualung Helix 1st stage
Reliable air delivery
The Helix 1st stage is a balanced, diaphragm-controlled stage that ensures smooth and effortless breathing at any depth. Regardless of cylinder pressure, this 1st stage provides you with a constant, comfortable airflow.
Well insulated 1st stage
Equipped with the patented ACD technology, the 1st stage is well protected against water and impurities both underwater and above water. In addition, the Helix 1st stage is very well protected against freezing, as it is equipped with a cold water kit, a dry kit that protects the stage against the ingress of cold water and thus against freezing. Therefore, the Helix pro regulator is ideally suited as a cold water regulator.
Compact dimensions and well-placed ports
Lightweight and compact, this Aqualung stage will not overburden your luggage. The well thought-out placement of the 4 medium pressure ports, which are positioned in a T-shape on the 1st stage, ensures optimum hose routing. In addition, you will find 2 high-pressure ports for the finimeter and transmitter on the Helix 1st stage.
Aqualung 2nd stage Helix
Lightweight and very comfortable 2nd stage
Made of robust yet very light materials, the Helix 2nd stage is very comfortable in the mouth even on long dives. It is equipped with a very practical exhaust tee that directs the exhaled air bubbles away from the diver's field of vision.
In addition, this 2nd stage has a very comfortable Comfo-Bite mouthpiece made of very soft and durable silicone, with an ergonomic shape to avoid any fatigue and tension of the jaw during diving and to ensure a secure hold, even in strong currents.
Very comfortable breathing
This pneumatically balanced 2nd stage allows you to breathe very comfortably and evenly even at greater depths. The stage is equipped with a large venturi switch that you can easily operate even when wearing thick neoprene gloves.
Good cold water protection
The Helix 2nd stage has a patented heat exchanger that protects the valve mechanism, dissipates the cold and prevents ice crystals from forming inside the stage. So even in cold water you are in good hands with the Helix regulator.
This high-quality Aqualung regulator is of course joined by an equally powerful Aqua Lung Helix Octopus, which delivers the same performance as the regulator's primary 2nd stage.
Good cold water performance and pleasant breathing comfort
This pneumatically balanced alternative air supply is also equipped with the same heat exchanger around the valve, making it fully cold water compatible. The pneumatically balanced mode of operation provides comfortable breathing resistance in an emergency.
No accidental free-flow
With a Venturi lever, this Aqua Lung Octopus can prevent accidental free-flow when submerged when the Octopus is not in use.
And, as befits an octopus, it comes with a highly visible 1m. long yellow hose and yellow purge button.
