Aqualung Regulator Package: Leg3nd + Gauges + BCD Hose

Aqualung's Leg3nd takes an already high-performing regulator platform and delivers it in its purest form — the same breathing characteristics as the Leg3nd Elite and Leg3nd MBS, in a streamlined package built for divers who want dependable, effortless performance without extra complexity. The familiar venturi switch now features an updated, ergonomic design: overmoulded with a soft-touch elastomer, it gives precise control over the venturi effect, letting you dial in a natural freeflow or contain it as conditions demand. Designed and made in France. Paired with your choice of Miflex gauge setup and a Miflex BCD hose, this package gives you a complete, precision breathing system ready to slot straight into your existing rig.

At the heart of the package is the Aqualung Leg3nd Regulator Set. The first stage is built around an over-balanced diaphragm design that is fully environmentally sealed — isolating internal components from moisture and contamination, and automatically increasing working pressure as you descend to maintain optimum breathing effort at depth. Three dedicated anti-freeze systems work in combination: a Permanent Dry Chamber that keeps inner components isolated from the outside environment, deep heat-exchanging ribs that create a large heat exchange surface area to prevent ice formation on the mechanism, and an over-moulded cap that delays icing over the external diaphragm. The Auto Closure Device (ACD) seals the first stage inlet automatically whenever the regulator is disconnected from a cylinder, keeping the filter clean, protecting internal lubrication and making the regulator safer for elevated oxygen percentages. Ergonomically shaped DIN and Yoke screws with bi-material Soft Grip surfaces make tank changes straightforward even with cold hands, and perfectly positioned HP and MP ports provide optimal hose routing throughout. The second stage carries the updated Venturi Adjustment Switch as its headline feature — an overmoulded, ergonomically designed lever that precisely controls airflow between "MIN" (higher inhalation effort, ideal to avoid freeflow) and "MAX" (lower inhalation effort, maximum performance), operable even while wearing gloves. The pneumatically balanced valve automatically compensates for increased ambient pressure as you go deeper, while a redesigned front cover with radial openings and widened channels reduces peak inspiratory flow by an impressive 20% and actively resists free-flows in strong currents. A heat exchanger helps prevent ice forming on the valve inlet, and a streamlined bi-material air channel deflector lowers exhalation effort throughout the dive. The overmoulded purge button has a wide surface area for easy operation, a tool-less mouthpiece clamp makes mouthpiece changes quick and waste-free, and the patented Comfobite mouthpiece reduces jaw fatigue on longer dives. A flexible, lightweight Aqua Flex hose with dual protectors completes a second stage that feels as good as it performs.

Completing the breathing system is the Aqualung Leg3nd Octopus, paired to match the primary second stage and built to the same standard. A dependable, easy-to-operate backup air source for you and your buddy.

Connecting your regulator to your BCD is the Miflex Xtreme BCD Hose, fitted with a standard 3/8" quick-release coupler suitable for most BCDs, wings and drysuits. Flexible, lightweight and flow-rate tested to EN 1809:2014 standards, it routes cleanly and reliably across any setup.
