All You Need to Know About the Aqualung Legend Elite Regulator: Standout Features
The Legend Elite comes packed with features that make it one of Aqualung’s top-performing regulators. It blends advanced engineering with diver-focused details that improve both safety and comfort. Below are the features that stand out the most when you take it into real dive conditions.
Auto Closure Device (ACD)
The first stage has Aqualung’s Auto Closure Device. When you remove it from the tank, the inlet automatically seals. This keeps water, dust, and contaminants from getting inside. For traveling divers, it’s a small detail that saves you from costly maintenance issues down the line.
Cold-Water Protection
The Legend Elite is built for demanding environments. The first stage has an environmentally sealed dry chamber, deep ribs, and overmolded caps to reduce ice formation. Combined with a heat exchanger on the second stage, it handles freezing conditions reliably. Cold-water divers will notice the difference in both performance and peace of mind.
Adjustable Breathing Controls
The second stage is pneumatically balanced and comes with both a Venturi switch and a cracking effort knob. These allow you to fine-tune breathing resistance. For example, when swimming against current at depth, you can open airflow for effortless breathing. When on the surface, you can close it down to prevent freeflows.
ComfoBite Mouthpiece
The ComfoBite mouthpiece is designed to reduce jaw fatigue on long dives. It has a unique palate bridge that holds the regulator in place without requiring you to bite down hard. On multi-dive days, this makes a noticeable difference in comfort.
High Performance at Depth
Tested at 50 meters under heavy workload, the Legend Elite delivers a low work of breathing at just 0.70 joules per liter. This translates to steady, easy breathing even when gas pressure drops low near the end of a dive. Technical and deep divers will appreciate this kind of reliability.

4.0/5
Value for Money
This is a premium regulator, priced at the higher end of the market. What you get in return is excellent performance in both warm and cold water, durability, and comfort. For advanced recreational and technical divers, the investment makes sense. For casual divers, it may be more regulator than you’ll ever need.
What We Like:
✅ Outstanding Breathing Performance
The balanced first and second stage deliver smooth airflow at all depths. Even when tank pressure is low or during heavy exertion, breathing remains effortless. On deeper dives past 30 meters, this consistency stands out.
✅ Cold-Water Reliability
The environmentally sealed first stage, combined with a heat exchanger and anti-freeze design, makes this regulator dependable in cold or icy waters. Divers who explore alpine lakes or winter seas will find it reliable against freeflows.
✅ Adjustable Controls
The combination of a Venturi switch and inhalation effort knob allows you to fine-tune airflow. For example, while swimming into current, opening up the airflow reduces breathing effort. On the surface, dialing it back prevents freeflow.
✅ Comfort for Long Dives
The ComfoBite mouthpiece and lightweight second stage help reduce jaw fatigue. After multiple dives in a day, the comfort difference compared to bulkier regulators is clear.
✅ Durability and Protection
The Auto Closure Device protects the first stage from dust, salt, and moisture when not connected. This extends the regulator’s lifespan and reduces the chance of corrosion or costly service issues.
What We Don't Like:
❌ High Price Point
At over $1,000, the Legend Elite sits at the premium end of the market. For casual divers who only dive a few times per year, the cost may be hard to justify.
❌ More Features Than Some Divers Need
Not everyone will take advantage of all the fine-tuning options. Beginners may find the extra adjustments unnecessary and prefer a simpler setup.
❌ Weight of First Stage
The first stage, especially in the yoke version, is heavier than some competing models. Traveling divers who count every gram may prefer a lighter option.
❌ Regular Servicing Costs
Although service centers are widely available, maintaining a high-end regulator can still be costly compared to budget models. Frequent divers need to factor this into long-term ownership.
The Verdict
The Aqualung Legend Elite is a regulator built for divers who want premium performance and reliability in all conditions. Its smooth breathing, cold-water protection, and fine-tuned controls make it especially appealing to advanced recreational and technical divers.
Travelers may find the weight of the first stage a drawback, and the price is higher than many alternatives. But if you dive regularly and need a regulator that performs just as well in warm tropical reefs as it does in icy waters, the investment is worthwhile.
For serious divers looking for a dependable, comfortable, and long-lasting regulator, the Legend Elite earns its place as one of the best options available.
