1. A detector for calculating a depth of a buried conductor, the detector comprising:

  • a first antenna;

    a second antenna having its axis parallel to an axis of the first antenna and spaced a distance s from the first antenna;

    a third antenna having its axis parallel to the axes of the first and second antennas and spaced a distance 2s from the first antenna and a distance s from the second antenna;

    means for comparing magnetic fields at the first and second antennas to produce a first compared value;

    means for comparing magnetic fields at the second and third antennas to produce a second compared value; and

    means for calculating the depth of said buried conductor based on the first and second compared values.
