Abstract
A detector for calculating a depth of a buried conductor is provided. The detector includes first, second and third antennas and a microprocessor. The second antenna has an axis parallel to an axis of the first antenna and is spaced a distance s from the first antenna. The third antenna has an axis parallel to the axes of the first and second antennas and is spaced a distance 2s from the first antenna and a distance s from the second antenna. The microprocessor is configured to compare magnetic fields at the first and second antennas to produce a first compared value, compare magnetic fields at the first and third antennas to produce a second compared value, and calculate the depth of said buried conductor based on the first and second compared values.
