US Patent 7232389 Wounded animal tracker

A Device for Locating a Wounded Animal for mounting on an arrow that has a head and a shaft. The Device is mounted on the head adjacent the shaft. A collar with a circular cross section has a plurality of prongs preferably mounted equi distant about the collar. The prongs are located at an acute angle to the collar. A signaling unit is located in each prong. The prongs are perforated adjacent the collar so as to break off easily. Upon impact of the arrow, at least one of the prongs breaks off and sticks in the animal. A transmitting unit in the prong permits ready location of the wounded animal.
