Kopie_von_What is EMFAD ?

The EMFAD - measuring method

• is based on the evaluation of variations of electromagnetic field data caused by anomalies in the subsoil.

It can locate :

• conductive materials, such as metal, pipes, barrels, cables, reinforced concrete, electrolytic effluents, etc.

• irregularities like cavities, graves, faults, shafts, ground fills, deposits, caves, tunnels, landfills.

The EMFAD - Technology has been successfully deployed in practice under various different climatic and geological conditions by professionals as well as by hobby researchers.

Fields of application predominantly are archeology, geophysics, geology, hydrology and treasure loacating ( treasure hunting ) in very different application areas as archeological sites, industrial waste sites and waste deposits, building lots, mining ares, street - construction sites, military practice sites and other soil investigations.

Data output / exchange from EMFAD - UG12 - PRO to a Notebook ( or PC ) via RS - 232 or USB port interface for data processing with the evaluation- and presentation software EMFAD - Scan - PRO.
