Abstract From the Canadian patent
A method and apparatus for tracking an arrow and/or game animal shot in the sport of archery hunting is disclosed. The arrow contains a radio-frequency transmitter in a circuit also containing a power supply and an inertia-activation switch in the shaft thereof.

Once shot the, inertia-activation switch momentarily closes causing, the transmitter to transmit a signal. The archer carries a radio-frequency receiver with a directional antenna and a magnitude indicator and earphone coupled thereto to allow tracking and retrieval of the arrow and game animal.
