Abstract
A hunting arrow tracking system includes a tubular housing removably connectable to an arrow shaft and enclosing a battery-powered transmitter. The batteries are disposed in a container in the housing which is spring biased against a piezoceramic transducer which generates a trigger signal in response to longitudinal acceleration or deceleration of the arrow to set a latch for connecting the battery to the transmitter, thereby causing it to transmit a low duty cycle pulsed signal. The transmitter is connected to a strip antenna which extends the length of the arrow shaft and is adhesively secured to the outer surface thereof. A directional receiver receives the transmitted signal and indicates the direction from which it is being received. The latch can be reset by passing a magnet over the arrow to activate a reed switch.
