Method for locating, and locating device

A method for locating a locatable object hidden under a surface to be searched using a locating device, the method comprising:

• receiving, with a receiving device of the locating device, at least one coupling signal that is dependent on the locatable object;
• acquiring a first value of the at least one coupling signal;
• specifying the first value as a background subtraction value;
• acquiring at least one second value of the at least one coupling signal;
• recalibrating the background subtraction value with the at least one second value in response to at least one second value being less than the background subtraction value;
• recognizing a valid background subtraction value in response to detecting that the locating device and the surface to be searched have been moved relative to one another by at least a predefined distance;
• and
• suspending the recalibrating in response to recognizing the valid background subtraction value.

A locating device for locating a locatable object hidden under a surface to be searched, the locating device comprising:

• a receiving device configured to receive a coupling signal from the locatable object;
• and
• a control device configured to:
• acquire a first value of the coupling signal;
• specify the first value as a background subtraction value;
• acquire at least one second value of the coupling signal;
• recalibrate the background subtraction value with the at least one second value in response to the at least one second value being less than the background subtraction value;
• and
• suspend the recalibration in response to recognizing a valid background subtraction value.
