Product Information
This package pairs the Aqualung LEG3ND MBS Dive Regulator with the Aqualung LEG3ND Octopus, giving you a matched primary and backup breathing setup built around the same core design. At checkout you can choose which LEG3ND regulator anchors the package: LEG3ND MBS, LEG3ND Elite, or the standard LEG3ND, each a complete first and second stage set.
The featured LEG3ND MBS adds the Master Breathing System to the second stage, putting venturi control and inhalation resistance adjustment behind a single lever so you can move from a free-breathing setting at depth to a dive-ready setting that resists free flow at the surface. Its first stage is an over-balanced sealed diaphragm design that raises intermediate pressure as you descend to keep air flowing, backed by an Auto Closure Device that seals the inlet whenever the regulator isn't connected to a cylinder, protecting the internal parts from contamination and corrosive water. The Comfo-Bite mouthpiece's bridged palate design stays seated without constant clenching.
The LEG3ND Octopus serves as the alternate air source and shares the same pneumatically balanced second-stage architecture as the primary regulator, so a donated air source breathes the way you're already used to rather than dropping to a lower standard when it matters. Its high-visibility yellow hose and front cover make it fast to locate in an out-of-air situation, and a venturi lever limits free flow while the octopus hangs unused. Both regulators use the Comfo-Bite mouthpiece for a consistent, secure fit.
- Master Breathing System combines venturi control and inhalation resistance adjustment into a single control on the LEG3ND MBS second stage
- Auto Closure Device keeps the first stage inlet shut when disconnected, protecting internal parts from contamination and corrosive water
- Over-balanced sealed diaphragm first stage raises intermediate pressure with depth to maintain flow
- Comfo-Bite mouthpiece uses a bridged palate design that stays seated without clenching
- Integrated dry chamber and deep-rib heat exchanger design help prevent ice forming on the first stage in cold water
- LEG3ND Octopus uses the same pneumatically balanced second-stage architecture as the primary regulator, so a donated air source breathes the way you're used to
- High-visibility yellow hose and front cover on the octopus make it easy to locate in an out-of-air situation
- Venturi lever on the octopus limits free flow while stowed and gives a performance boost at depth
- Choose LEG3ND MBS, LEG3ND Elite, or LEG3ND as your primary regulator, each paired with the same matched Octopus

Frequently Asked Questions
What is the Aqualung LEG3ND MBS dive regulator?
The LEG3ND MBS adds Aqua Lung's Master Breathing System to the LEG3ND second stage, combining venturi control and inhalation resistance adjustment into a single control so you can switch between a free-breathing setting at depth and a flow-resistant setting at the surface. It pairs an over-balanced sealed diaphragm first stage with a pneumatically balanced second stage, and it's nitrox-compatible up to 40% O2 out of the box.
What does the LEG3ND MBS regulator set include (first stage and second stage)?
The set is the first stage and MBS second stage together: an over-balanced sealed diaphragm first stage with 2 HP and 4 MP ports, and a pneumatically balanced second stage with the Master Breathing System control. It comes with two mouthpieces (a Comfo-Bite installed, plus a standard bite-wing mouthpiece) and an included lip shield.
Is the Aqualung LEG3ND MBS available in a DIN configuration?
Yes. The spec sheet lists a DIN first-stage weight (747 g) alongside a yoke weight (957 g), so the LEG3ND MBS is offered in both DIN and yoke versions.
What's included in this bundle, and does it come with an octopus?
This bundle includes one Aqualung LEG3ND MBS Dive Regulator (first and second stage set) and one Aqualung Octopus LEG3ND. The octopus shares the same pneumatically balanced second-stage design as the primary regulator, with a high-visibility yellow hose and cover so it's easy to locate in an out-of-air situation.
