The pole-dipole array contains four collinear electrodes. One of the current (source) electrodes is installed at an “effective infinity” distance, which is approximately five to ten times the survey depth. The other current electrode is placed in the vicinity of the two potential (receiver) electrodes. This geometry is utilized because it reduces the distortion of equipotential surfaces.
