Abstract
A hunting arrow comprises a shaft, a tip end, fletching, and a nock having a hollow cavity with arrow locating structure disposed therein. The arrow locating structure includes a normally open electrical circuit having a power source, a time delay, a device for producing an audible signal upon expiration of the time delay countdown, and a switch adapted to close the electrical circuit extending from inside the cavity to the outer side of the nock. Upon actuation of the switch the time delay starts its countdown and upon expiration of such countdown the device for producing an audible signal is energized whereby an audible signal pinpoints the location of the arrow.
