Patent

CA 2115689

A compound bow drawcheck is disclosed for a compound bow which has a bow string connected to a bow cable and a rotatable cable guide over which the bow cable is guided, whereby the cable guide rotates in a predetermined relationship with the bow cable when the bowstring is drawn and between a first position wherein the bow string is not drawn and a second position wherein the bow string is at a desired draw. The draw check includes a detector which detects when the cable guide is in the second position and an indicator which produces asignal when the second position is detected. The detector is either an electrical switch operated by mechanical interaction between a contact strip on the cable guide and electrical contacts on the bow limb carrying the cable guide, an optical sensor detecting a mark on or a hole in the cable guide or a sensor detecting a magnetic strip on the guide. The indicator includes a signal light or LED or a buzzer. The draw check is more accurate than prior art devices and detects underdraw as well as overdraw.
