Aqualung LEGEND Dive Regulator + LEGEND Octopus Set

Aqualung LEG3ND Dive Regulator + LEG3ND Octopus Set

Premium Breathing Performance in All Conditions

The Aqualung LEG3ND Regulator Set pairs the flagship LEG3ND primary regulator with the matching LEG3ND Octopus to deliver elite-level performance, reliability, and comfort—even in extreme cold-water conditions. Engineered for divers who demand precision and control at depth, this balanced diaphragm system provides effortless breathing, advanced thermal protection, and full user adjustability.

The first stage features Aqualung’s Auto Closure Device (ACD) and environmental sealing, while both second stages are pneumatically balanced for smooth, natural breathing. The LEG3ND Octopus offers the same performance as the primary second stage, in a high-visibility configuration for secure gas sharing.
