 Aqua Lung Legend LUX Supreme Review Video

But first, below is a video review of the Aqua Lung Legend LUX Supreme done by the guys over at In the video, you can get a closer look at the regulator and some of its most important features.

Aqua Lung Legend Key Features

The Legend range of regulators (more about the different models below) share pretty much the same major components and performance.

Excellent Breathing Performance

It features an over-balanced diaphragm which delivers greater intermediate pressure at depth than your standard balanced system. This design helps compensate for the increased density of the gas at depth by allowing a greater volume to pass through the system, allowing you to have much better breathing performance the deeper you dive.


Rated for Cold Water Diving

The first stage is also environmentally sealed to prevent water, contaminants, as well as silt and sand to enter the spring chamber.  This allows the regulator to perform consistently between servicing. It also prevents ice from building up around the main spring, which makes it perfect for diving in extremely cold water conditions. The spring chamber is also surrounded by heat exchange fins which help add further cold water protection.


 Auto-Closure Device (ACD) 

Another cool feature of the second stage is the ‘Aqua Lung’s Auto-Closure Device’ (ACD) system. This automatically seals the regulator inlet once it has been taken off the cylinder. This further protects the first stage by keeping unwanted corrosive water and other contaminants out of the first stage, especially if you forget to put on the dust cap after use.

Optimized Second Stage

The second stage has been made smaller and lighter for better comfort and to help reduce the strain on your jaw. It features a Pneumatic balanced system which makes for smooth and effortless breathing. The ergonomically designed exhaust tee defects bubble out of your field of vision and help to reduce exhalation efforts.

Master Breathing System (MBS)

It also features Aqua Lung’s ‘Master Breathing System’ (MBS), which combines both the Venturi effect and inhalation adjustment into one easy to use knob (Only available on the Legend LUX and LX Versions). In the “Min” position it will prevent unwanted free-flows when the regulator is not in your mouth or on the surface, while in the “Max” position it will deliver the best breathing performance.

Aqua Lung Legend Versions

The Legend comes in three different models, the Legend LUX, the Legend LX, and the standard Legend, each of which has ‘Supreme’ versions. The Supreme regulators are specially adjusted for diving in the extremely cold water and equipped with a lip shield to keep your lips warm. There is also a Twilight version of The Legend that is geared expectantly for women divers.

So what’s the difference between models?

Let take a closer look.

Aqua Lung Legend LUX

Aqua Lung Legend LUX Yoke Regulator

This is Aqua Lung’s flagship version and features stylish pink gold and black PVD finish. The colored finish is not only for looks, the PVD is much harder to scratch than traditional chrome plated regulators. The second stage also features Aqua Lungs Master Breathing system, which combines both the Venturi effect and inhalation adjustment into one. The Legend LUX and LUX Supreme are also the only versions that are supplied in a branded regulator case.

Aqua Lung Legend LUX Supreme

Aqua Lung Legend Review: Unparalleled Performance and Reliability 1

This version has the exact same features and performance of the Legend LUX. However, it’s specifically tuned for diving in the extreme conditions of cold water. It also comes equipped with a removable lip shield, which keeps streaming cold water away from your lips, keeping them warm. Like the Legend LUX, this regulator also features Aqua Lung’s Mater Breathing System to further fine tune your breathing.

Aqua Lung Legend LX

Aqua Lung Legend LX Scuba Regualtor

The Legend LX sports the same features and performance you would expect from the Legend LUX version, but without the pink gold PVD finish. The first stage, second stage trim, and heat exchanger are all protected from the elements by a high-polished chrome plated finish instead. This makes it a little more affordable than the  LUX version. Just like the Legend LUX, the Legend LX is also equipped with Aqua Lung MBS control for easy breathing adjustments.

Aqua Lung Legend LX Supreme

Aqua Lung Legend LX Supreme

The Legend LX Supreme is specifically adjusted for cold water diving, but still, deliver the same performance you would expect from the LUX and LX. It also has a matte chrome finish instead of the high-polished chrome of the LX. It also features Aqua Lung’s MBS control and has a removable lip shield to keep your lips warm.

Aqua Lung Legend 

Aqua Lung Legend Regulator

The standard Legend has the same high-polished chrome plated finish as the LX on the first stage and heat exchange, but the second stage is fully black to differentiate between the two models. This model also lacks the MBS Control. Instead, it uses a Venturi switch to redirect airflow in the second stage.The breathing effort on the second stage is preset so you don’t have to worry about making adjustments while diving.

Aqua Lung Legend Supreme

Aqua Lung Legend Review: Unparalleled Performance and Reliability 2

The Legend Supreme has the same features and performance as the standard Legend. However, it has been specifically adjusted for cold water diving. Instead of high-polished chrome, it sports a matte chrome finish. It also features a removable lip shield to keep your lips warm when diving in cold water.

Aqua Lung Legend XL Twilight 

Aqua Lung Legend Review: Unparalleled Performance and Reliability 3

You should expect the same performance that you would expect from the existing Legend LX model.  However, it has been designed specifically for women divers. It is exactly the same as the Legend LX. But instead, the Twilight includes a smaller Comfo-bite mouthpiece and a lighter second stage to help reduce jaw fatigue. The second stage tips are also purple to give the regulator a more feminine look.

Aqua Lung Legend XL Twilight Supreme

Aqua Lung Legend Review: Unparalleled Performance and Reliability 4

The Legend LX Twilight Supreme and LX Twilight share pretty much all the same features. However, the Legend LX Twilight Supreme is tuned specifically for cold water diving. The first stage also has a matte finish instead of high-polished chrome, and it also comes with a removable lip shield to help keep your lips warm while diving the cold water.

What We Like

All models of this regulator get a high rating from reviewers online and are praised for their ease of breathing and performance. It is exceptionally easy to breathe from and that the lightweight 2nd stage is really comfortable and easy to adjust.

We also like its durability,  all important parts of the regulator are made from metal and not plastic. 

Also, many times I’ve e seen divers forget to replace the dust cap on their regulator before dunking it in water. If this happens, the ACD System will keep water out of the first stage. The ACD System also help keep internal parts lubricated and operating a peak performance, as well as making it safer to use with a higher percentage of oxygen. This is a feature we wish more regulator would have. 

The legend also has a comfortable mouthpiece, and the lip shield on the supreme version actually helps to keep your lip warmer in cold water. 

What We Don’t Like

There honestly nothing much we didn’t like about the Aqua Lung Legend, except for the price. It is a bit expensive (LUX) and not ideal for every diver, but you do get what you pay for.

However, a few divers recommended sticking to a Legend octopus as other octopuses tend to free flow at depths. This is credited to the overbalanced nature of the regulator.

If you dive in confined spaces like cavern and caves, then the harder to scratch LUX version would work great. The LX would make a great all-around regulator. The regulator Legend is great if you are on a budget and can manage without having adjustable inhalation settings. 

Who Is This Regulator Designed For?

Although there many versions of this regulator, none of them are cheap.  They are all high-performance regulators made from high-quality materials and designed for durability and reliability. So, the price range might be out of your range if your and entry-level diver just starting out. If you can afford it though, you cannot go wrong with this regulator.
