A hunter alert device (9) for use by hunters when hunting wild game consists of transmitter means (21), receiver means (22), an antenna (11), a transceiver controller (20), and an indicator means (12). The device (9) operates by intermittently transmitting a modulated radio frequency signal through antenna (11) and listening for radio frequency signals transmitting from alert devices worn by other hunters. When a signal is detected, the receiver means (22) determines whether the signal is within a predetermined range of the hunter and, if so, activates the indicator means (12) to warn the hunter.
