ABSTRACT:
A device for detecting and compensating field distortion in underground line locators by means of mapping the field-strength of the field generated by electrical currents within the buried line. Signals from the underground structure can be mapped with respect to the position of the device. From the map, distortions from the expected signals can be determined, indicating interference from other structures or errors in detected location of the structure.
