Abstract
A battery powered radio transmitter of a cross-sectional diameter substantially equal to the cross-sectional diameter of an arrow shaft is positioned in series between the head and nock of a metallic hunting arrow. The transmitter section of the shaft is light in weight so as not to affect the normal flight characteristics of the arrow. The shaft portion between the transmitter and the nock acts as the antenna for the transmitter. A switch is provided for operation of the transmitter. A portable directional radio receiver of the same frequency as the transmitter is utilized by the hunter to track the spent arrow.
