ABSTRACT:
A device which functions to locate preselected items which are remote from a user. The device comprises two parts; a hand held device and multiple sensors/chips which are applied to objects the user desires to locate. The hand held devices contains a control panel selector buttons for each multiple sensors/chip it is desired to locate. When a preselected button is depressed, a transmitter sends signal containing preselected code. The signal is received by a receiver in each multiple sensors/chip. The receiver in each multiple sensors/chip reads the code and if a match is obtained the receiver enables an audio tone generator in the multiple sensors/chip to send a tone through an audio speaker. The multiple sensors/chip further, transmits a signal to the hand held device which is received by a second receiver and decoded. The second receiver matches the code with the multiple sensors/chip selected and enables a second audio tone generator to send a second tone through a second speaker. Both tones are controlled to become louder the closer the hand held device is to the desired multiple sensors/chip. The multiple sensors/chip has an attachment device permitting attachment to various articles to be found. The hand held device and multiple sensors/chip are powered by a power source.
