A system and method for locating an object, the system including a signaling device for mounting on an object, the signaling device including a signaling transceiver transmitting an identification signal, and a signal locator including a locator transceiver for receiving a signal directly from the signaling device, a direction sensor for sensing a direction towards which the signal locator is pointing, a locator controller determining, from the received signal and from the sensed direction, a direction from which the identification signal is received by the signal locator, and an indicator indicating that direction. Preferably, the signaling device further includes a signaling controller coupled to the signaling transceiver, which automatically switches the transmitter between a contact mode, to establish contact with the signal locator, and an operational mode, to permit determination by the signal locator of that direction, after contact has been established. |
