Patent abstract
A remotely actuated trail marker apparatus includes a transmitter unit designed to be carried by a hiker or hunter, which selectively broadcasts an interrogation signal throughout a predetermined range. One or more associated receiver units are adapted for pre-positioning at specific trail waypoints or a final destination. Each receiver unit generates a user sensible reply signal, such as self-illumination, in response to receiving the interrogation signal.
