Geo-survey units are harmonic detectors of terran design. Used prominantly by the Confederate Exploration Corps, they are usually used to read electromagnetic returns of vespene gas. However, their sensors can also be adjusted to pick up different signals such as mineral composition. By extension, this makes them able to detect laser trips provided one knows the exact mineral composition of the crystals that produce them.[1]
