A suite of advanced tools for accurate detection of buried metallic objects, landfill delineation, and ore deposits.
Electromagnetic (EM) instruments utilize electromagnetic transmitters and receivers for the detection of subsurface metal and lateral and vertical variations in electrical conductivity. The EM instruments can detect both ferrous and non-ferrous metals. Some models, such as the EM61-MK2 by Geonics is relatively insensitive to interference from nearby surface metal such as fences, buildings, cars, etc., yet it detects a single 55-gallon drum at a depth of over 10 feet beneath the instrument.
With electromagnetic methods, data can be viewed by the operator for on-the-fly detection, or downloaded to a laptop for processing analysis, and mapping. The instruments transmit and receive signals by means of induction and do not require direct ground contact.
