Slightly smaller and lighter, the new Legend regulators provide improved performance with a modified yoke knob for better drainage and a spring-loaded Auto Closure Device (ACD) that snaps shut automatically to prevent water from getting into the device.

Both the Legend LX and Legend LUX have a patented dual control system, rather than a knob and switch, to control the opening effort. The Master Breathing System (MBS) easily controls both the venturi and opening effort automatically and simultaneously, allowing for smoother, more natural breathing.
