Abstract

A multipurpose, non-fluid, electronic level mechanism featuring an inhibitor, and emitter and a receiver. The inhibitor is mounted from the inhibitor bracket and in operation blocks a laser from the emitter to the receiver, unless the device is at a level position on a selected surface. If the device is at a level position on the selected surface, the laser from the emitter passes through an aperture in the inhibitor and is receiver by the receiver, which indicates that the device is level on the exterior of the device's body.
