This is for the passionate, the explorers for whom diving is more than a sport, it is a state of mind. Here is the third generation of Legend. The most advanced, innovative and ergonomic generation of regulators ever created. These masterpieces of engineering mark the plunge into a new way of discovering by ensuring the highest breathing comfort whether you are exploring in cold or warm water.

Aqualung is synonymous with the modern scuba regulator. Over 70 years of innovation have gone into making scuba regulators that are safer and easier to use than others on the market. An Aqualung scuba regulator offers you comfort, ease of breathing, control and peak performance. Aqua Lung and the scuba regulator share a rich history, and now is your chance to play a part. Choose the right scuba regulator to ensure your next dive is comfortable and safe. Aqualung has developed diving regulators built for new and experienced divers, as well as for a range of diving conditions.

Aqualung's premier and iconic line of Legend regulators feature an overbalanced diaphragm designed to provide excellent breathing performance. The Leg3nd range features premium engineering, with such features as Aqualungs, unique Auto-Closure Device (ACD) and the revolutionary Master Breathing System (MBS) for simple breathing comfort control. With the ACD, divers don't have to worry that water or silt will enter the first stage. Since 1943, Aqualung has been the expert in scuba regulators. Now you can carry on the spirit of that first dive with an Aqualung dive regulator that will perfectly suit your diving needs. If you want high-performance features and ease of breathing the Leg3nd MBS is the regulator for you.

Auto Closure Device (ACD) - keeps corrosive water out of the first stage inlet by automatically closing as the Legend is removed from the cylinder valve. This prevents internal lubrication from washing away. Safer for elevated percentages of oxygen. Unique over-balanced, diaphragm design results in superior performance at depth. 2 HP ports and 4 MP ports are angled for optimum hose routing. An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out. Available in yoke connector. Compatible with up to 40% O2 right out of the box.

Exceptional cold-water performance is achieved by modernizing Aqualung's three anti-freeze properties: 1. Where there is no moisture, there is no ice: The Leg3nd's integrated dry chamber keeps inner components clean and dry by isolating them from the outside environment. 2. Deep ribs create a large heat exchange surface area that helps prevent ice forming on the mechanism (+30% vs Glacia/+70% vs Legend 2) 3. The new over-molded cap delays ice forming over the external diaphragm. Ergonomically shaped yoke screw made of a bi-material soft grip surface provides a better hold when installing or removing the first stage - especially with cold hands.

Pneumatically balanced second stage results in smooth, easy breathing. New front cover opening channels allow water to flow sideways over the diaphragm. Radial openings to prevent free-flows when diving in strong currents. Openings widened to reduce peak inspiratory flow by an impressive 20%. New over-molded exhaust cover made of elastomer with a soft touch effect. Over-molded air purge. Wide surface area makes regulator purge easier. Purge depth controller optimizes air flow with minimum effort. A venturi switch helps prevent free-flow at the surface and when the regulator is out of the diver's mouth. The opening effort is pre-set in a fixed position so the diver doesn't have to worry about adjusting the regulator during the dive. Patented Comfo-Bite mouthpiece virtually eliminates 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 (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. The ergonomic exhaust tee channels the exhaust bubbles out of your field of vision. The design also contributes to a reduction in exhalation effort. Air Chamber deflector. Directs the air flow evenly during the inhalation phase. Streamlined bi-material deflector lowers the exhalation effort. Attached to a 29" (73.7cm) braided Aqua Flex hose. These hoses are lightweight and extremely pliable which eliminates any tugging on the mouthpiece and come with dual protectors. The regulator comes with an owner's manual.

To compliment the Leg3nd regulator family, Aqualung created the Leg3nd Supreme Octopus. This high-visibility, yellow version of the Leg3nd second stage is ideal to complete your system. Pneumatically-balanced second stage results in smooth, easy breathing. A venturi switch helps prevent free-flow at the surface and when the regulator is out of the diver's mouth. The opening effort is pre-set in a fixed position so the diver doesn't have to worry about adjusting the regulator during the dive. The silicone mouthpiece with ergonomic bite wings and comfort. 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. Excellent cold-water performance due to highly efficient heat exchanger surrounding the valve.

The ergonomic exhaust tee channels the exhaust bubbles out of your field of vision. The design also contributes to a reduction in exhalation effort. Attached to a 39" (99cm) yellow high visibility braided Aqua Flex hose. These hoses are lightweight and extremely pliable which eliminates any tugging on the mouthpiece. Regulator has high-visibility yellow purge cover and accent pieces. Like the primary the Leg3nd Supreme Octopus is compatible with up to 40% O2 right out of the box.
