Abstract

The invention relates to a method for detecting objects (12) that are enclosed in a medium (10). According to said method, a test signal (18) that makes it possible to obtain information about the position of the enclosed object (12) is generated via at least one transmission coil (14) and at least one receiving conductor loop system (16) which are inductively coupled to each other. The frequency (fM) of the test signal (UM) is modified in accordance with the signal intensity of the detected test signal (18). The invention further relates to a measuring apparatus, especially a hand-held locating device (24, 124), for carrying out the disclosed method.
