1. An apparatus for measuring and detecting a magnetic signature of a magnetically detectable object from a distance comprising:

  • one portable sensor group for detecting the magnetic signature, the portable sensor group consisting of three gradient sensors, each of the three gradient sensors adapted to independently measure both a magnitude and a direction of the magnetic signature, a first of said gradient sensors measuring an axial gradient in the vertical direction, a second of said gradient sensors measuring a first horizontal gradient in the vertical direction, and a third of said gradient sensors measuring a second horizontal gradient in the vertical direction; and

    a signal output device connected to each of the three gradient sensors.
