Electrical Resistivity Imaging (ERI)
All OKM articles related to Electrical Resistivity Imaging (ERI) are listed here. Many of our metal detector pages are tagged with Electrical Resistivity Imaging (ERI).
The GeoSeeker utilizes a geoelectrical measurement procedure based on Schlumberger to read the soil resistivity. Based on that ground resistance the detector is capable to locate underground water deposits, water-bearing gravel and groundwater level as well as cavities like caves, tunnels, chambers and the like. Thus the geophysical detector can be deployed as water finder or cavity detector at the same time.
Geoelectrical water detector and cavity detector for resistivity measurements up to 250 m depth.
This combined device of the Rover C and the Cavefinder looks for deep laying metals and caves.
An ancient wine cellar has been located on an old french castle by using the geophysical instrument Grailfinder. This old cave which is estimated from the 15th century by experts and so has an unexpected high historical value, has been located in a depth of 21 meters. Planete Detection IDS has led this professional underground research and located the entrance of this void. By presence of the first french channel TF1 they demonstrated the metal detector Grailfinder, found the cellar and finally went down with the cameramen and discovered 4 big rooms. "It was just wonderful!" so IDS.
In 2014 the team of OKM Emirates FZE (UAE) and its local business partners from GDI - Geological Detection and Imaging (Lebanon) tested the recently announced cavity and water detector GeoSeeker. Supported by an former adviser of the geological department in Lebanon several practical tests were performed in the mountain area of Beirut. In heavy mineralized rocky soil the team was able to detect underground water deposits in a depth of 70 - 90 meters.
