ABSTRACT:
A bow draw indicator and sighting device mounted on a bow provides signals which enable the archer to adjust the bow vertically and horizontally to assure proper aim. Also an arrow draw indicator signal is provided which signal operates only when the bow is in proper vertical position. The device is battery powered. The bow draw and the vertical signal is either an audible signal or a light emitting diode. The horizontal (elevation) signal is in the sight and comprises light emitting diodes at the upper and lower portions of the sight. The device is small and light enough to be easily mounted on the bow and to have utility for both hunting and target purposes and can be used with aluminum or other electrically conductive arrows.
