Abstract
The invention relates to an arrangement for operating a geophysical locating device by means of evaluating magnetic field changes, comprising flux gate sensors, an amplifying circuit as well as an evaluating and display unit.According to the invention, two interspaced flux gate sensors oriented in the same direction are provided in a probe, wherein the sensors furnish output voltages which are identical with regard to polarity.The output signals are fed each to a level alignment circuit as well as to a low-pass filter. There is a connection to an input of a differential amplifier at the respective outputs of the low-pass circuits which is connected to the input of a limiting amplifier. The evaluation signal can be tapped at the output of the limiting amplifier for further processing.
