Features of Aqualung Leg3nd DIN

Product description of Aqualung Leg3nd DIN diving regulator set

Description summary

Experience ultimate diving performance with the AQUALUNG Leg3nd DIN regulator set. Featuring an auto-balanced, auto-closure device first stage for optimal breathing and contamination protection, it excels in cold water with advanced anti-freeze properties. The second stage boasts improved water flow, reduced inspiratory effort, and a patented Comfobite mouthpiece for comfort. Its ergonomic design and durable construction ensure reliability for every dive

When performance is your highest priority, LEG3ND is the answer. The LEG3ND shares the same breathing characteristics with the LEG3ND ELITE and LEG3ND MBS. The familiar venturi switch now features an updated and ergonomic design. Overmolded with “soft touch” elastomer, the ergonomically designed switch perfectly controls the venturi effect, either allowing or containing a natural freeflow.

Features:

First Stage

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

Second Stage

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.
- Flexible and lightweight Aqua Flex hose with dual protectors.

The use of this material requires specific training given by a diving instructor. The user must also read the user manual carefully. TRADEINN and/or the brand are not responsible for damages resulting from improper use. By formalizing the purchase, you declare that you have read and agree with the safety warning.

Good regulator, I have another one bought 20 years ago but some part was broken (2nd stage), so I decided to buy new one. I always trust its quality

The regulator arrived in two weeks. This is the cheapest model from the Leg3nd family. I have been using the old Legend Glacia model in the harshest conditions for many years and have no complaints. I decided to update my winter diving gear. I think the regulator will be no worse than the old one.

After 20 years without problems, it's time to change the regulator for the same model, although some things have changed. I keep the old one as a reserve regulator because it continues to work. The shipment of Diveinn correct and in the indicated time.

Albert

I would just like to confirm that the regulators are a full set? (hard to tell from the photo) ie. comes with first and second stage, as well as hp inflator, pressure gauge and hoses etc. Could you please ask them to quote for a full Octopus to include, the first stage, primary and secondary regulator, SPG, and inflator hose.

Answer of Antoine

The kit only includes the first stage and the second stage with its hose. There´s no pressure gauge, no hose for the direct system, and even less of an octopus. This makes sense considering the price.

Answer of Xavier

Hello, it comes with the first and second stages connected by a HP hose only. No octopus, no pressure gauge, no HP hoses, no pressure gauge, or direct system; you need to get the full pack. Have a nice day, Xavier.

Answer of Pierre

This kit only includes the first stage, hose and second stage. It does not have the pressure gauge to be purchased separately and the direct system hose to inflate the stab
