ABSTRACT:
An electrical detection system for locating a position of interest in a medium which is electrically conductive includes a signal generator, a source, a sink and at least two probes. The probes are disposed in the medium equidistantly spaced from either the sink or the source. A signal generated by the generator flow from the sink and to the source and will also flow to the probes. The probes are connected to input terminals of a comparator to thereby compare the signal strengths at the probes. The probes are movable to different positions in the medium to determine a cross-over position such that, at the cross-over position, the perpendicular bi-sector of the line joining the probes indicates the point of interest by pointing in the general direction thereof.
