ABSTRACT:
An archery aiming device includes in combination an illuminated bowsight connected to a battery operated electronic module, an automatic mode rotary switch mechanism, and a optional selectable manual mode trigger switch mechanism. The electronic module and bowsight attach to a conventional tournament sight, the rotary switch mechanism attaches to a conventional bowsight, and the optional trigger switch mechanism attaches to a convention trigger device. The bow carries a negative charge from the battery. Selection of either the automatic or the manual mode serves to complete the electrical circuit to operate the illuminated bowsight. The automatic mode additionally tells the archer that he/she has reached precise full draw anchor position prior to shooting the arrow. A draw length calibrator is provided for setting drawing length.
