The Aqua Lung Core Supreme provides amazing breathing and durable build quality in a lightweight travel-ready design. Made to Aqua Lung’s uncompromising standards the Core Supreme takes on many of the features found in the high-end Legend range in a more budget friendly offering.

Weighing less than 900g in the heavier Yoke configuration the Core Supreme is perfect for travelling, without compromising on performance.

Ready to take on sub 10°C waters, the Core Supreme features heatsinks around the inlet valves to prevent ice build-up and provide clear, comfortable air to breathe.

Aqualungs ‘Auto Closure Device (ACD) prevents the internal lubrication from flushing out of the 1st stage. This increases its resistance to ice and increases the lifespan of the regulator.

Both the 1st and 2nd stages of the regulator provided balanced air pressure for a consistent, clear output of air throughout your entire dive. Designed to take-on harsh underwater water environments the main spring chamber in the 1st stage is environmentally sealed to prevent ice build-up and keep contaminants out. This ensures its long-lasting and reduces the cleaning required.

Trickling down a great deal of the technology and features from Aqualung’s more advanced Legend regulators the Core Supreme offers outstanding performance from a mid-range regulator. Built to last, the Core Supreme qualifies for Aqualungs ‘Free Parts of Life’ scheme, ensuring you’ll be able to keep diving with it for years to come.


Auto Closure Device (ACD)
Keeps corrosive water out of the first stage inlet by automatically closing as the Core is removed from the cylinder valve
This prevents internal lubrication from washing away
Safer for elevated percentages of oxygen.

The balanced diaphragm first stage provides superior, consistent performance
The pneumatically-balanced second stage results in smooth, easy breathing
Available in yoke (3300 psi / 232 bar max) or din (4350 psi / 300 bar max)

The T-shape of the first stage optimizes the location of the 4 MP ports and 2 HP ports.

Uses parts that are common to other Aqua Lung models for easier servicing
The easy-to-grip venturi lever prevents unwanted freeflow 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.

Compatible with EAN 40 new, out of the box.

Equipped with Aqua Lung’s patented Comfo-bite™ mouthpiece along with a reusable mouthpiece clamp.

Resistant to freezing when diving in waters colder than 50°F / 10°C.
