This newly developed active metal detection system is primarily used for the detection of large metal objects such as underground deposits, barrels and bombs. The special features of the PKI 9135 Active Metal Detection System consists in its selectivity regarding small metal objects buried close to the surface and – in comparison to active metal detectors – its excellent detection range on large objects (transmitter effect). For conventional operations, there is a galvanometer and an audio alarm integrated into the electronic box. Furthermore the system has an analogue data output and can therefore also be linked to an external data logger to allow data recording.
