  • Patent number: 7300367
    Abstract: An assembly for tracking an animal which has been shot by an arrow. A shank portion of an arrow is received in a bushing which in turn receives a housing for a transmitter. The housing is retained on the bushing during arrow flight by an elastomeric ring. Upon impact of the arrow with the animal, the elastomeric ring is dislodged, releasing the housing from the bushing. Associated with the housing are members which penetrate the animal to attach the housing to the animal. A hand-held direction finding receiver receives signals from the transmitter so that direction to the animal is determined.
