A searching system employs a global positioning system (GPS) and a wireless communication system to enable a second transceiver to trace the distance and the directions of a plurality of first transceivers. The first transceiver can automatically call the second transceiver user when the user of the first transceiver is at rest in excess of a predetermined interval or has a body temperature lower than a critical value. The user of the first transceiver can push an emergency button on the first transceiver to call the user of the second transceiver for help.
