The Core Supreme regulator is light-weight and travel friendly but also a good cold water regulator - perfect for British diving

Aqua Lung Core Supreme Regulator

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.

Key Benefits

First Stage:

  • Travel-Ready - The Aqualung Core Supreme is compact and lightweight. This makes it ideal for storage and for travel. In the heaviest combination (1st stage Yoke) the regulator weighs less than 900g.
  • Auto Closure Device (ACD) - Aqualung’s Auto Closure Device keeps corrosive water out of the first stage inlet. When you remove the Regulator from the cylinder valve it seals, stopping water getting in.  This prevents internal lubrication from washing away, reducing the level of maintenance required on the Core. Furthermore, it’s safer when using higher percentages of oxygen, for greater flexibility.
  • Balanced Diaphragm Design - The balanced design of the 1st stage ensures the regulator breathes consistently and clearly through your entire dive, for easier breathing.
  • Optimised Hose Routing - The T shape design of the 1st stage allows you easily route your hoses.
  • Environmentally Sealed - The environmental seal around the Spring Chamber keeps contaminants out of the system. This ensures the system remains clean for longer and requires less maintenance.
  • Tough Construction - The main body of the 1st stage is constructed from Chrome coated Marine brass ensuring it’s nearly impervious to corrosion if cared for properly.
  • 40% 02. Out Of The Box - The Core Supreme regulator is compatible with tanks of up to 40% oxygen without any additional modifications.
  • Yoke or Din. Your Choice - Whatever your preference or requirements, the Core Supreme regulator is available in both Yoke or Din configurations.

Second Stage:

  • Balanced Second Stage - The balanced second stage ensures clear and consistant breathing throughout your dive.
  • Venturi Switch - The Core Supreme is fitted with a Venturi switch. This allows you to limit or adjust the free flow of air to the mouthpiece so you don’t waste oxygen when it’s out of your mouth.
  • Pneumatically-Balanced Second Stage - The Pneumatically-balanced second stage allows for smooth and easy breathing.
  • Patented Heat-Sink Design - A Heat-Sink surrounds the valve mechanism. This dissipates the extreme cold caused by gas expansion while drawing in as much warmth as possible from the ambient water around for it for maximum longevity of the regulator.
  • Super Comfortable Mouthpiece - Aqualung’s Comfobite™ features a silicone bridge that sits on the palate of your mouth. This provides support for the mouthpiece to ensure a comfortable, drag-free fit.
  • Lightweight Build - The Core Supreme is constructed from heavy-duty plastic. It’s super lightweight making the Core Supreme easy to handle and travel with.
