About Aqua Lung Legend ACD Supreme Regulator

The New Line of Legend Regulators Crafts the Future with Innovative Technology and Sleek Cosmetic Appeal The new Legends are Smaller and Lighter making for a more Comfortable Dive Whether you are Jet-Setting to an Exotic Location or Diving your Local Spot, the Legend will give you the Confidence to Dive like a Pro and look like a Rock Star Be a Leader Be an Icon Be a Legend

The Legend ACD Supreme First Stage is an Over-Balanced Diaphragm Design As the Diver Descends, the Intermediate Pressure coming out of the First Stage Increases at a Rate Faster than Ambient Pressure The Over-Balancing Compensates for the Increased Density of the Breathing Gas at Depth The Balanced Diaphragm, Chrome Plated Marine Brass First Stage Regulator is inherently Environmentally Sealed The benefit of this type of First Stage design is that none of the Delicate Internal Parts are Exposed-to-Contaminants such as Salt, Sand, Chlorine or Pool Acids These Environmental Contaminants can cause Corrosion and Mineral Deposits to form on the Internal Mechanism Deteriorating Regulator Performance A Diaphragm First Stage Regulator requires Less-Maintenance then Regulators that allow the Contaminates to enter the Internal Mechanism

The Diaphragm of the First Stage Regulator forms a Membrane Barrier between the Environment and the Internal Mechanism The Diaphragm Membrane Transmits Pressure Changes to the Mechanism keeping the Internal Parts cleaner and Contaminant Free The Legend ACD Supreme is also designed as a Cold Water Regulator The Supreme Cold Water Version is Resistant to Freezing when Diving in Waters Colder than 50°F/10°C The Regulator accomplishes this by sealing off the Spring Chamber keeping the First Stage Completely-Sealed-Off from the Environment adding a Second-Layer of Corrosion Resistance and Prevention of Freezing in Cold-Water-Use

The Legend ACD Supreme takes this Protection One-Step-Further with the Auto-Closure Devise (ACD) The ACD keeps Corrosive Water out of the First Stage thereby ensuring Top Performance The ACD Seals the Regulator's Inlet Fitting, as soon as the Regulator is Removed-from-the-Cylinder Valve This will keep Water and Contaminants Out-of-the-Regulator's First Stage during Rinsing and Storage It allows the First Stage to Maintain Peak Performance Over-Time, will Retain-its-Internal Lubrication-Longer and makes the First Stage Safer for Nitrox Use

When the Regulator is Clamped onto the Scuba Cylinder, the Inlet Crown Retracts thereby Exposing the Gas Inlet in the Center Valve Post This provides a Steady Flow of Breathing Gas to the First Stage without any Restrictions The Legend's unique Forged Body is Triangular T-Shaped for better Hose Routing The T-Shape uses Less-Brass making it more-Compact The First Stage Regulator has 4 Low Pressure Ports 3/8" UNF Thread and 2 High Pressure Ports 7/16 UNF Thread The Ports are angled for Optimum Hose Configuration The Legend Regulator is Compatible with Nitrox Mixtures up to 40% O2 Out-of-the-Box

The Legend ACD Supreme Second Stage Regulator is a Pneumatically Balanced Design A Pneumatically Balanced design delivers Gas at a Constant Pressure so Work-of-Breathing remains Effortless Independent of Depth or Tank Pressure In Short a Pneumatically-Balanced Second Stage results in Superior Ease-of-Breathing The Second Stage is equipped with an Easy-to-Grip Venturi Lever that Stops unwanted Free-Flow when the Regulator is Out-of-your-Mouth The Legend ACD Supreme Second Stage comes with Aqua Lung's Comfo-Bite Mouthpiece which Reduces Jaw Fatigue The Legend ACD Supreme also has a Lip-Shield on the Second Stage Mouthpiece Outlet to keep the Divers Lips Warm in Cold Water Diving and a Reusable Mouthpiece Clamp

To further prevent Freeze-Ups in Cold Water the Legend Second Stage is equipped with a Heat-Exchange Inlet Fitting The Ribbed Heat-Exchange Inlet helps Warm-the-Air-Flowing to the Second Stage Reducing the possibility of Second Stage Freezing The Regulator Housing is manufactured from a Durable Techno-Polymer with an Over-Molded Front Cover The Mouthpiece, Exhaust Valve and Diaphragm are Silicone The Legend ACD Supreme Regulator is equipped with a 3/8" Threaded 29" (73 7 cm) Braided Aqua-Flex Low Pressure Hose, weighing less than 5 oz (141 75 g), provides Flexibility, Comfort and Excellent Pack-Ability The Legend ACD Supreme Regulator weighs 42 9 oz (1,216 g), comes with an Owner's Manual and is covered by a Limited Lifetime Warranty

          Comments about Aqualung Aqua Lung Legend ACD Supreme Regulator:

          I have owned this regulator for over 125 dives and I have nothing but great things to say about it. I have had it in the cold dark waters of the Great Lakes to the warm clear water of the Caribbean and Pacific with no problems whatsoever. Have even swam against strong current, pushing a heavy drysuit and panting like a dog for over 30 minutes and could not "over breathe" this regulator...

              I've used down to 140', 50F water. It breathes very well, and doesn't have that silly gold look.

                Went down to about 90 feet with the Legend ACD Supreme in 49 degree waters, and the regulator performed brilliantly. I felt no difficulty in getting air out of the regulator. The lip shield definitely kept the area around my mouth warmer, and the mouthpiece was very comfortable. If you are diving in warmer waters, you can easily remove the lip shield.

                Questions about this item:

                Shopper  Why Did You Choose This?
                TJ T  Built for use in our Alaska waters (winter water temp 34 to 38 degrees). Want to minimize problems when grabbing king crab!
                Shopper  What is the difference between the Legend and the Legend LX?
                PATRICK M  First off it is chrome plated. But I think the parts in the regulator might be a better quality. I would recommend looking at the technical specs for each and comparing each.
                Shopper  Will the Calypso/Titan Octo work with this Reg?
                Steve S  Yes, it will work just fine.
