ABSTRACT:
An electronic vertical angle sensing and indicating device for use on aiming systems is provided for bow sights and for other aiming sights for projectile launchers. Improved vertical level measurement and display minimizes the left-right drift of a projectile by sensing and indicating to the user when the projectile launcher is tilted slightly prior to release of the projectile. The vertical level indicator is easily viewed within the field of direct or near direct vision and focus of the eye in a reduced profile that does not distract the operator from the task of accurately aiming the projectile is provided. One embodiment of the present invention positions the signal indicators in the far-field of view of the eye, so that all of the signal indicators, the sighting means and the distant target being viewed are simultaneously in focus or near-focus.
