Abstract (en)
An apparatus for locating small articles comprises a transmitter and a receiving unit. The transmitter is capable of sending a receivable signal. The receiving unit is attachable to a small article and comprises means for receiving the transmitted signal and emitting a perceptible signal in response to the transmitted signal. The receiving unit is sufficiently small not to significantly alter the nature of the article to which it is attached.
