Aqualung Legend 3 Elite Regulator Set

Aqualung Legend 3 Elite Regulator Set

The Leg3nd Elite gives you separate control of Venturi assistance and inhalation effort. Paired with an over-balanced first stage, a permanent dry chamber and automatic inlet closure, it suits divers who want detailed adjustment alongside protection for regular warm- and cold-water diving.

Features and benefits

• Over-balanced first stage. The diaphragm mechanism increases intermediate pressure slightly faster than surrounding pressure as you descend, helping compensate for denser breathing gas at depth.
• Dry environmental chamber. The sealed chamber keeps water and sediment away from the first-stage spring mechanism and supports resistance to freezing in cold water.
• Automatic inlet closure. The inlet closes when the first stage is disconnected, helping keep water and debris out. Continue to protect the connection with its clean, dry dust cap.
• De-icing features. Heat-exchange ribs and the overmoulded cap help limit ice formation around the first-stage mechanism.
• Balanced second stage. Pneumatic balancing reduces the force needed to open the demand valve, helping the second stage respond smoothly as you inhale.
• Inhalation-effort adjustment. The adjustment knob lets you change the effort needed to start a breath, so you can tune the response within the regulator’s operating range.
• Venturi control. The lever changes airflow assistance inside the second stage. Use the pre-dive setting for surface handling and the dive setting as directed in the manual.
• Comfo-Bite mouthpiece. The silicone palate bridge supports the second stage with less need to clench your jaw, which can make longer dives more comfortable.
• Flow channels in the front cover. Side-facing openings reduce the direct force of moving water on the diaphragm, helping the regulator cope with current.
• Flexible Aqua Flex hose. The lightweight hose bends easily around the diver’s equipment, helping reduce pull at the mouthpiece.
• Heat exchange. The heat exchanger transfers warmth from the surrounding water to the valve area, helping counter the cooling that occurs as gas expands.
• Matching Leg3nd octopus. The balanced alternate second stage has a heat exchanger and visible yellow detailing, giving the set a clearly identifiable backup air source.

Setup and compatibility

Connection: DIN, Yoke. Choose the fitting that matches your cylinder valve and its pressure rating.

Care, rinsing and storage

After each dive, connect the assembled regulator to a scuba cylinder and open the valve to pressurise the system. Keep it pressurised while fully submerging the first stage, second stages and connected hoses in fresh water. This allows thorough cleaning of the exposed components and hoses while helping prevent water entering the internal air passages, where it can cause corrosion and damage. Keep the cylinder secure throughout cleaning.

For routine cleaning, Dive Gear Australia recommends Cressi Neoclean Wetsuit Wash Neoprene Cleaner 500 mL or Revivex Wetsuit Shampoo 10 oz to help remove salt, chlorine and everyday residue. Dilute according to the cleaner’s label, then rinse thoroughly with fresh water.

Keep the regulator pressurised throughout washing and rinsing. Lift it out of the water and dry the first stage and cylinder connection before closing the cylinder valve, releasing the pressure and disconnecting. Fit the clean, dry dust cap, then allow the regulator to dry in the shade. Store it with the hoses loosely curved, without sharp bends or tension.

Before each dive, inspect the mouthpiece, hoses and connections for wear or damage. Have your regulator serviced by an authorised Aqualung technician at the interval specified in its manual, or sooner if it leaks, is damaged or its breathing performance changes. Leave internal adjustments and repairs to a qualified technician.
