Abstract
A system for locating an underground utility line using a beacon positioned within a downhole tool. The beacon comprises a magnetic sensor formed from one or more ferrite rods. The rods are arranged such that no rod is orthogonal to the longitudinal axis of the beacon housing. The magnetic sensor detects the presence of an underground utility line and sends a signal to an above-ground tracker indicating that a line has been detected. An above-ground locator may be used to determine the position of the line relative the beacon, so that the downhole tool may be steered away from the line.
