Aqualung Helix Pro Regulator: Key Features and Benefits
It is a basic replacement for Aqualung's Core Supreme Regulator. The Helix Pro is a mid-range regulator designed to be a great all-around regulator for beginner to intermediate recreational diving. Below are some of its core features:
Helix Pro First Stage
- Balanced Diaphragm – This technology ensures consistent performance at varying depths and pressures, protecting the internal components from harsh external environmental conditions. With this feature, you can expect smooth, effortless breathing no matter how deep you dive.
- Patented ACD technology – It incorporates an automatic closure device (ACD) that prevents corrosive water from entering the first stage inlet, ensuring longevity and reliable performance. This also prevents internal lubricant from washing away allowing the regulator to be serviced every two years.
- Environmental Seal – The environmental seal prevents water infiltration into the first stage even when it is not under pressure, making it a great choice for cold-water diving.
- T-Shaped Design – The T-shape design of the first stage optimizes the location of four low-pressure (LP) ports and two high-pressure (HP) ports. This design also makes the regulator streamlined and compact.
Helix Pro Second Stage
- Pneumatically Balanced – The second stage is pneumatically balanced, delivering smooth, consistent performance and making it easier to breathe at different depths.
- Venturi Lever – The easy-to-grip venturi lever prevents unwanted free flow at the surface while boosting performance on deeper dives.
- Heat Exchanger – The patented heat exchanger surrounding the valve mechanism helps to dissipate the cold caused by gas expansion while drawing in warmth from the water.
- Comfo-Bite Mouthpiece – It also comes equipped with Aqualung’s patented Comfo-Bite mouthpiece which offers a comfortable and secure fit. A reusable clamp replaces the need for pesky zip ties.
