A hunting or target arrow comprising of a shaft, fletching, and specially designed plunger type arrow head that after impact will automatically activate a sound emitting device. The foremost tip of the arrow head which is slidable extends slighty from its main body, being the normally open circuit position. At impact the tip slides into the main body which houses the energy source and closes the electrical circuit which in turn activates the sound emitting device at the rear of the arrow shaft.
