This Aqua Lung Leg3nd MBS regulator set pairs the yoke-configured Leg3nd first stage with a Leg3nd MBS second stage and a matching octopus, supplying a complete primary and alternate air source from one platform. Because both second stages share the same architecture, a donated regulator breathes the same way the primary does.
The over-balanced sealed diaphragm first stage raises intermediate pressure as depth increases so gas delivery stays consistent deep in the dive. The Master Breathing System merges venturi and inhalation resistance adjustment into a single control, and Comfo-Bite mouthpieces on both second stages hold position without jaw clenching. The yoke connection fits 3,300 psi (232 bar) cylinder valves.
