Aqualung Legend 3 Elite Second Stage
Take direct control of your breathing feel with the Leg3nd Elite second stage. Separate Venturi and inhalation-effort controls let you adjust each function independently, while the Comfo-Bite mouthpiece helps support the regulator without a tight bite.
This listing is for the separate second stage, for use in a compatible regulator assembly.
Features and benefits
- 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.
Setup and compatibility
This is a separate regulator component. Pair it with a compatible first or second stage and the required hose; the complete assembly must be configured and checked by a qualified technician. The hose and hose protector are not included.
Care, rinsing and storage
Clean this component as part of a complete, correctly assembled regulator system. 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.
