Abstract
A sonde array that is useful in locating buried utilities includes at least three substantially mutually orthogonal antennas. Each antenna includes a substantially cylindrical ferromagnetic core, an insulating layer surrounding the core, and a length of a conductor wrapped around the insulating layer to form a coil. The coils of the antennas are substantially identical.
