Breathing you fine-tune yourself, crafted for challenging dives
Aqualung crafted the Leg3nd Elite for diving in challenging and extreme environments, and says it gives exceptional breathing comfort and performance in any dive condition. Advanced divers can fine-tune the breathing resistance with independent micro-adjustments to match how they breathe. It is made with stainless-steel parts, and the controls sit intuitively at your fingertips. The over-balanced first stage has an Auto Closure Device (ACD) and a permanent dry chamber. Designed and made in France.

Aqualung says the over-balanced (also called auto-balanced) design overcompensates the interstage pressure to reduce your breathing effort, regardless of depth or tank pressure. Two HP ports and four MP ports are positioned for optimal hose routing.
When the regulator is off the cylinder valve, the ACD keeps the inlet shut, so debris and corrosive water stay away from the internal parts. It helps maintain oxygen compatibility, preserve the internal lubrication and keep the inlet filter clean and dry. A dust cap attached to the body protects the inlet fitting and the ACD from impacts.
A permanent dry chamber isolates the internal parts from the water outside, keeping them clean and dry and improving freeze resistance in cold water. Deep ribs give the first stage a large heat-exchange surface, and the overmolded cap delays ice forming over the external diaphragm. In the second stage, a heat exchanger prevents ice forming on the valve inlet. The DIN and yoke screws have a two-material Soft Grip surface that helps with cold hands.
Set the Venturi switch to MIN for a higher inhalation effort, ideal to avoid free-flow, or to MAX for a lighter breath; you can work it even in gloves. The cracking-effort adjustment fine-tunes breathing for different dive conditions. Wide radial openings in the cover let water flow sideways over the diaphragm, which Aqualung says prevents free-flows in strong currents and reduces cracking effort by 20%. An air channel deflector spreads the airflow evenly and lowers exhalation effort.
The Comfo-Bite mouthpiece, patented by Aqualung, has a palate bridge that reduces jaw fatigue and is made of hypoallergenic silicone. You change mouthpieces without tools, using a reusable clip, so no plastic goes to waste. The purge button is overmolded, the exhaust cover has a soft-touch finish, and the Aqua Flex hose is flexible and lightweight, with dual protectors.
It is how the first stage connects to the tank valve, so match the valves you dive with. Aqualung lists the first stage at 747 g (26 oz) in DIN and 957 g (34 oz) in INT (yoke), with a maximum working pressure of 300 bar in DIN and 232 bar in yoke. Not sure? Ask us on LINE.
The Venturi switch at MIN gives a higher inhalation effort, which Aqualung calls ideal to avoid free-flow; MAX gives a lighter breath, and you can switch it in gloves. The cracking-effort adjuster fine-tunes breathing for different dive conditions. The two adjust independently.
Aqualung marks it for cold and warm water. The first stage has a permanent dry chamber that improves freeze resistance, deep ribs for a large heat-exchange surface and an overmolded cap that delays ice on the external diaphragm. The second stage has a heat exchanger that prevents ice forming on the valve inlet.
Aqualung lists it as compatible up to 40% O₂ when new, out of the box (21% in Europe). Planning to dive nitrox? Ask us first.
