1. In archery hunting, a system for tracking game, including:
- an arrow comprised of a shaft joined to an arrow head at one end thereof and a nock at the opposite end thereof for allowing driving of said arrow by an archery bow, said arrow including a hollow metal shaft part supporting said arrow head which includes metal parts capable of emitting a radio frequency signal;
transmitting means inside said hollow metal shaft part and connected electrically to the metal parts of said arrow head for emitting a radio-frequency signal whereby said metal parts of the arrow head act as a primary antenna;
a secondary antenna electrically connected to said transmitting means while extending within a portion of the hollow metal shaft part of the arrow; and
power supply means for providing power to said transmitting means.

Abstract
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. The circuit is of a size and weight so as not to alter the flight characteristics of the arrow. 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.

10. A method for locating an arrow launched by an archery bow, said method including the steps of:
-
aiming an arrow containing a radio-frequency transmitting means and a secondary antenna within a hollow metal arrow shaft part at a target, propelling the arrow towards said target causing a primary antenna formed by metal parts of an arrow head at one end of the arrow to emit a radio frequency signal; detecting said signal by a radio receiver which receiver includes a directional antenna to allow detection of said signal transmitted by either of said primary antenna or said secondary antenna. - View Dependent Claims (11, 12)
