Aqualung LEGEND MBS Dive Regulator + LEGEND Octopus Set

Aqualung LEG3ND MBS Dive Regulator + LEG3ND Octopus Set

Simplified Control with Maximum Breathing Performance

The Aqualung LEG3ND MBS Regulator Set pairs the advanced LEG3ND MBS regulator with the matching LEG3ND Octopus, offering divers a complete system designed for simplicity, comfort, and superior cold-water performance. The MBS version features Aqualung’s Master Breathing System—a single control knob that simultaneously adjusts both Venturi and inhalation resistance for intuitive, one-handed tuning during the dive.

The overbalanced diaphragm first stage is environmentally sealed and equipped with Auto Closure Device (ACD), while both second stages are pneumatically balanced for smooth, effortless airflow. The LEG3ND Octopus mirrors the same performance standard, making this a robust and streamlined system for cold and deep dives.
