ABSTRACT:
A transmitter attachment for hunting arrows includes a hollow tubular member which is removably mounted between the arrowhead and shaft of a conventional hunting arrow. The tubular member has a transmitter mounted in one end, and a battery slidably mounted between a pair of spring contacts in the other end. The battery is mounted so as to slide forward into electrical contact with a coil spring, which closes an electrical circuit to energize the transmitter, when the arrow hits the target or the ground. Thus, the combination of battery and contacts forms a type of inertia switch. A directional receiver is utilized to locate the arrow. The transmitter is deactivated by tapping the nock-end of the arrow against the ground--which slides the battery out of contact with the coil spring.
