Built to Aqua Lung’s impeccable standards the Legend Supreme offers impressive breathing performance, even in extremely cold underwater environments.

Aqua Lung Legend Supreme Regulator

Built to Aqua Lung’s impeccable standards the Legend Supreme offers impressive breathing performance, even in extremely cold underwater environments. The Legend Supreme features the same incredible spec as Aqua Lung’s flagship LX Supreme Models except for a Venturi switch on the 2nd stage rather than the more advanced MBS dual control valve seen on the top end regulators.

The high performing first stage is designed to take-on harsh underwater water environments. The main spring chamber is environmentally sealed to prevent ice build-up and keep contaminants out. This ensures its long-lasting and reduces the cleaning required.

The Pneumatically-balanced second stage provides smooth, easy breathing for a comfortable diving experience. Combined with the over-balanced diaphragm design the Legend Supreme offers superior breathing performance at depth. A Venturi switch on the 2nd stage allows you to control and reduce the free flow of air to the mouthpiece. This ensures you don’t waste oxygen when you’re at the surface or not wearing the mouthpiece.

A silicone bridge on the mouthpiece sits across on the top of your palate for support. It’s super comfortable and eliminates mouth fatigue. A cover around the mouthpiece provides extra thermal protection for your lips making it ideal for colder dives.

Built to last, the 1st stage is constructed from chrome coated Marine Brass ensuring it’s corrosion and abrasion resistant. The 2nd stage has been PVD coated for greater durability and corrosion resistance.

Key Benefits

First Stage:

  • Auto Closure Device (ACD) - Aqua Lung’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 Legend. Furthermore, it’s safer when using higher percentages of oxygen, for greater flexibility.
  • Superior Performance At Depth - Aqua Lung’s unique over-balanced, diaphragm design results in superior performance at depth and helps to prevent the valve from freezing.
  • Optimum Hose Routing - Two High pressure and 4 Mid Pressure Ports allow you to attach any gear you need. The ports are angled to achieve optimal and comfortable hose routing.
  • 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.
  • Anti-Freeze Design - The main Spring Chamber is environmentally sealed preventing ice build-up. This ensures you always experience smooth airflow, even during deeper and colder dives.
  • 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.
  • 40% 02. Out Of The Box - The Legend 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 Legend Supreme regulator is available in both Yoke or Din configurations.

Second Stage:

  • Venturi Switch - The Legends 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.
  • Super Comfortable Mouthpiece - Aqua Lung’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.
  • 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.
  • Ergonomic Exhaust - The 2nd stage is designed to vent bubbles away from your field of vision for frustration free diving. The design also contributes to a reduction in exhalation effort.
  • 29” Braided Aqua Flex Hose - The 29” Braided hose is lightweight and robust. It’s extremely pliable which eliminates tugging on your mouthpiece for greater comfort.
  • Heavy Duty PVD Coating - A tough PVD Coating on 2nd stage body ensures it’s highly corrosion resistant and tough, reducing abrasion and scuffs.
