Aqualung Leg3nd Regulator Review

A reliable, cold-water-capable regulator that served as my primary for 80+ dives. It performed well in cold and warm water with no issues, but I switched to ScubaPro due to local service availability. I no longer own it.

Use: 80+ dives; primary regulator for over a year
Configuration: Long hose with necklace backup
Still in my kit: No

The Short Version

The Leg3nd was a dependable primary regulator for over a year, with comfortable breathing in cold and warm water and no performance issues across 80+ dives. I switched to ScubaPro because of local service availability, not because the Leg3nd let me down. I no longer own it, but its performance was not the reason I changed brands.

Would I buy it again? No, because my dive shop does not support the brand. If it did, I would have no hesitation using it as my primary regulator.

What Works

Reliable performance in cold and warm water
Smooth, comfortable breathing past 100 feet
No freeflows during my cold-water entries
Clean long-hose routing and comfortable necklace backup
Good build quality across 80+ dives with proper maintenance

What Doesn't

My local dive shop does not support Aqualung servicing
Somewhat bulky second stage and more weight than travel-focused options
Fewer accessories and aftermarket modifications than competing options

Why I Chose the Aqualung Leg3nd

I wanted a cold-water regulator for local Great Lakes diving that could also handle occasional travel. The Leg3nd offered easy breathing and cold-water certification without requiring environmental kits. At the time, my shop supported Aqualung, and the overall value felt right for a high-performance regulator.

It was not a budget regulator, but the pricing was reasonable for the performance I received. The practical problem came later, when local service support no longer fit my needs.

What It Is Like to Dive

Breathing: Breathing stayed smooth and consistent from the surface to past 100 feet. Setup was straightforward, and I did not encounter quirks or a learning curve in its operation.
Cold-Water Reliability: I had no freeflow incidents, including during cold-water entries. It handled cold quarries and warm-water diving without performance hiccups.
Mouthpiece Comfort: The standard mouthpiece worked well for me without jaw fatigue. Its sizing also worked with my standard rubber bungee necklace.
Trim and Routing: The long-hose arrangement did not interfere with trim or buoyancy control. Everything routed cleanly and stowed well, with no hose kinks or flow restrictions.

My Long-Hose Configuration

I used the Leg3nd in a DIR-style configuration with a long hose and a bungee necklace backup. It integrated smoothly, with no clearance problems or mouthpiece discomfort.

Primary: A 7-foot long hose routed under my arm and behind my neck.
Backup: A standard rubber bungee necklace that worked with the Aqualung mouthpiece.

I would not change anything about the way I configured it. The hose routing and backup placement both worked without adding friction underwater.

Ownership, Travel, and Service

The materials held up well across 80+ dives with proper maintenance. Its reliability was a strength, but the bulk and weight were less convenient than those of travel-focused regulators. That did not prevent me from using it for both local and travel diving.

The reason I moved to ScubaPro was access to service through my local shop. I did not have a personal reliability problem with the Leg3nd. For equipment that needs ongoing servicing, the support available where I dive mattered more than staying with a regulator that had otherwise worked well.

Who It Makes Sense For

Based on my use, it makes sense for cold-water divers who want one regulator for local diving and travel and value straightforward operation. Its breathing and long-hose compatibility were useful strengths rather than features I had to work around.

I would choose something else if my shop could not service Aqualung, which was my own reason for switching. I would also look at lighter options if minimizing travel weight were the priority.
