Aqua Lung Core Supreme Review Video

The guys over at Southern Maryland Divers did a great job of reviewing the Aqua Lung Core Supreme. In the review and unboxing, you can get a closer look at the regulator and some of its key features.

Aqua Lung Core Key Features

Auto Closure Device (ACD)

A neat feature of this regulator is the Auto Closure Device (ACD) which seals the regulator’s inlet as soon as it’s removed from the dive cylinder. This help keeps corrosive water and contaminants out of the First Stage during rinsing and storage.

This also helps maintain lubrication on internal parts, ensuring that the regulator works at peak performance over a longer period of time.

Comfo-bite™ mouthpiece

The Comfo-bite™ mouthpiece is specially designed to reduce jaw fatigue. This mouthpiece fits right into your denture and fixes itself on the roof of your mouth, so you won’t have to bite down to hold on to it and have jaw pain afterward. It also comes with a reusable clamp and a lip cover (Supreme version) that protects your lip from cold temperatures.

Heat Exchanger

The steel swivel that connects the rubber hose to the second stage, which also surrounds its valve mechanism, is framed with multiple heat sinks. They absorb the heat from the surrounding waters and dissipate the cold generated when the gas expands.

Venturi Switch

It also features a large Venturi switch that can easily be adjusted even while wearing thick gloves. The Venturi System is there to prevent unwanted free-flow on the surface while delivering optimum performance at depth.

The Aqua Lung Core Supreme is more tuned for cold water diving and is also environmentally sealed. It comes equipped with a lip shield on the second stage which many divers find effective at keeping your lips warm at cooler temperatures.

What We Like

The Core has a very simple, lightweight, symmetric design with an easy to push purge button that covers the entire face of the second stage. It offers exceptional breathing performance at a wide range of breathing rates and depth, leading to it winning Scuba Lab’s testers choice for 2015

However, the thing we like the most about this regulator is the ACD system. Especially after my regulator was accidentally dunked with the dust cap off. This is a feature I would love to see other manufacturers develop on their regulators. 

What We Don’t Like

It would be great if this regulator had an adjustable inhalation knob to fine tune your breathing resistance because it’s present on the Core. This is expected from regulators in this price range and does not affect the performance of the regulator in any way.

But, if having this feature is a must for you, its available on Aqua lung’s higher-end regulator the Legend LX and LUX and other high-end dive regulators like the Scubapro Mk25/A700 and the Sherwood SR2.

Who Is Aqua Lung Core Designed For?

The Aqua Lung Core is a great, lightweight, cold water (Supreme Version) regulator that delivers excellent breathing performance due to its balanced properties. Set at an affordable price point, it’s a great buy if you’re a new diver just starting out or if your upgrading your regulator system to a more modern lightweight design.

The normal version will work perfectly in all recreational diving conditions. However, if you are planning on diving in water colder than 50°F (10°C) then the Supreme version would be the best choice.
