Aqualung Helix Pro Yoke Regulator with Octopus

- Aqualung Helix Pro Yoke Regulator -
The Aqualung Helix Pro is a mid-range regulator that represents the DNA of Aqualung regulators. It is a balanced first and second stage design, offering superior, consistent performance. The regulator features the patented ACD technology that seals water out of the first stage inlet, preventing internal lubrication from washing away and making it safer for elevated percentages of oxygen.

The Helix Pro's balanced diaphragm chrome plated marine brass first stage is fully protected even when the regulator is not under pressure, and it can be serviced every two years. The pneumatically-balanced second stage provides smooth, easy breathing, and the T-shape of the first stage optimizes the location of the four low-pressure (LP) ports and two high-pressure (HP) ports. The regulator is compatible with EAN 40 new, out of the box.

The Helix Pro features an easy-to-grip venturi lever that prevents unwanted free-flow at the surface while giving a performance boost at depth. The heat exchanger (patented) surrounding the valve mechanism dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. The regulator comes equipped with Aqualung's patented Comfo-Bite mouthpiece installed with a standard bite wing mouthpiece, along with a reusable mouthpiece clamp.

The regulator weighs 33.44 oz (948g) and comes with a 29" (73.7cm) low pressure 3/8" threaded hose and owner's manual. It is available in DIN with a service pressure of 300 bars (4350 psi) maximum. The Helix Pro uses parts that are common to other Aqualung models, making it easier to service. Overall, the Aqualung Helix Pro is a reliable, high-performing regulator that is an excellent value for years to come.

- Aqualung Helix Octopus -
The Aqualung Helix Octopus provides the same great performance as the Helix Pro primary second stage with its pneumatically-balanced second stage that results in smooth, easy breathing. Thanks to its highly efficient heat exchanger, it is up to the rigors of cold-water diving. With its 39" (99cm) Hi-Viz yellow hose and front cover, it will be ready to provide life-sustaining air in an out-of-air situation. The easy-to-grip venturi lever prevents unwanted free-flow at the surface while giving a performance boost at depth. A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. The Helix Octopus is compatible with EAN 40 new, out of the box. Equipped with a silicone mouthpiece with ergonomic bite wings. Octo weighs 7.3 oz (207g) without the hose and comes with an owner's manual.
