More divers are breathing through the XLC second stage than any other regulator in the world. Its flawless exterior houses a level of engineering that its competitors cannot hope to match.

A combination of outstanding workmanship and superior design promises a lifetime of outstanding performance under even the most adverse diving conditions.

First Stage:

Uses a balanced-diaphragm mechanism. This results in ease-of-breathing and consistent performance while environmentally protecting the internal parts

The first stage is T-shaped as opposed to its in-line predecessor making it more compact and providing optimal hose routings

Features 1 HP port and 4 MP ports

The unique, forged body of the first stage uses less brass making it more compact and lighter weight

The outer skin provides impact protection as well as a cosmetic flair

Now uses a conical filter for better filtration

Accepts an optional ACD (auto-closure device) system

The yoke screw has been improved so it doesn’t trap water after the dive

Compatible up to 40% O2 when new, out of the box

Second Stage:

New, mid-size, high performance, demand valve second stage

Easy-to-grip venturi knob stops unwanted freeflow when the regulator is out of your mouth

Can easily be reversed from right-handed to left-handed configuration by an authorized Aqua Lung dealer without additional parts

Comes with Aqua Lung’s Comfo-bite mouthpiece which reduces jaw fatigue

A grid built into the exhaust tee creates finer exhaust bubbles for less noise and more stability

All new, easy purge front cover

A new, reinforced polycarbonate material makes this second stage stronger than its predecessor

The side openings on the front cover prevent freeflow when facing into currents or riding a scooter
