Abstract
A tool, such as a level, including audio and/or visual indicators is provided. The level may include one or more bubble level vials having a controller and a sensor. The visual indicators are associated with the vials. The controller is configured to activate the audio and visual indicators in repose to a signal received from the sensor. The controller illuminates the visual indicators for each vial when that vial indicates it is level or plumb.
