ABSTRACT:
An arrow that accepts standard target or hunting tips includes a radio signalling transmitter which emits a carrier signal that is receivable by a directional receiver for tracking and locating the arrow when released from a bow. The transmitter includes a carrier interrupting circuit operating at a rate that is inversely proportional to battery voltage which permits dynamically testing the battery prior to releasing the arrow. This provides reliable operation of the transmitter by insuring an adequate minimum charge in the battery. An electrical switch embodying the arrow tip as an actuator permits selectively connecting or disconnecting the battery from the transmitter to conserve the battery charge.
