Abstract
An arrangement is described for tracking a positional relationship between a boring tool and at least one in-ground line. A first transmitter generates a magnetic locating field from one of the boring tool or at least an underground length of the line. A receiver is carried by the boring tool if the field is generated from the line, or connected to the line if the field is generated from the boring tool, for detecting an intensity of the magnetic locating field indicative of the positional relationship between the boring tool and the line. A second transmitter is carried by the boring tool for producing a locating signal. A portable locator uses the locating signal to determine a position of the boring tool and indicates the detected intensity of the magnetic locating field.
