The Aqua Lung Leg3nd Stage 3 Regulator Set includes the new high performing Leg3nd regulator and a matching Leg3nd Octopus for excellent cold water reliability, a smooth breathe and style.
The Leg3nd is a fully balanced regulator system using an over-balanced diaphragm first stage for improved performance as you dive deeper. Cold water performance has been improved by adding extra deep heat exchanging ribs to the diaphragm assembly, the first stage is environmentally sealed to prevent water ingress and the diaphragm is further protected by an overmolded cap to delay ice formation.
The first stage is fitted with an Auto Closure Device (ACD) that effective prevents contamination and water from entering the first stage when the regulator isn’t pressurised on a cylinder. This helps to keep the filter clean, dry and free flowing, allows the internal lubrication to do it’s job for longer without collecting debris and dirt and by keeping the regulator cleaner it is also safer when using elevated oxygen percentages.
The first stage body features four low pressure ports and two high pressure ports, offering plenty of flexibility for diving with BCD & drysuit, and fitting an analogue gauge and wireless transmitter for a dive computer.
The second stage has been refined for better breathing comfort with subtle changes to the front cover, heat exchanger and valve to make the second stage inhale even better, perform better in strong currents and provide better cold water performance by transferring the cold generated by the decompressing gas into the surrounding water.
The second stage still features a venturi control with a ‘soft touch’ grip that controls the flow of air within the second stage, either directing it straight to the mouthpiece for maximum efficiency or forcing it to flow back towards the diaphragm to assist with closing the valve, effectively providing pre-dive and dive modes.
The mouthpiece has been given an easy to operate clamp that eliminates the use of the single use plastic zip tie and makes mouthpiece changes quick, simple and tool-less. The mouthpiece remains a patented Comfobite mouthpiece that reduces jaw fatigue and secures the second stage more comfortably.
When the first stage is not connected to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet shut to protect the first stage internal parts from contamination and corrosive water.
Preserves the internal lubrication
Keeps the inlet filter clean and dry
Safer for elevated percentages of oxygen
Exceptional cold-water performance is achieved by modernizing Aqua Lung’s three anti-freeze properties:
Where there’s no moisture, there’s no ice: The LEG3ND’s integrated dry chamber keeps inner components clean and dry by isolating them from the outside environment
Deep ribs create a large heat exchange surface area that helps to prevent ice forming on the mechanism (+30% vs Glacia / +70% vs Legend 2)
The new overmolded cap delays ice forming over the external diaphragm
Auto-Balanced (also known as Over-Balanced)
Progressive increase of the working pressure to maintain optimum breathing efforts: Depending on the diver’s depth, the working pressure of the first stage is automatically elevated to counteract the increased breathing air density
Ergonomically shaped DIN and YOKE screws made of a bi-material “Soft Grip” surface provide a better hold when installing or removing the first stage – especially with cold hands
Channeled YOKE screw to prevent water retention.
Specialized ACD Dust cap attached to the regulator body to protect the inlet fitting and the ACD system from impacts or damage
Perfectly positioned HP and MP ports provide optimal hose routing
New front cover opening channels allow water to flow sideways over the diaphragm
Radial openings to prevent freeflows when diving in stronger currents
Openings widened to reduce peak inspiratory flow by an impressive 20%
New overmolded exhaust cover made of elastomer with a “soft touch” effect
Overmolded air purge
Wide surface area makes regulator purging easier
Purge depth controller optimizes air flow with minimal effort
Patented Comfobite mouthpiece reduces jaw fatigue and secures the second stage more comfortably.
Detachable and reusable mouthpiece clamp allows a quick and simple tool-free mouthpiece change without plastic waste.
The enlarged heat exchanger helps to prevent freezing of the second stage mechanism
Air channel deflector
Directs the air flow evenly during the inhalation phase
Streamlined bi-material deflector lowers the exhalation effort
