Like GeoSeeker’s large brother, GeoSeeker Mini uses a Schlumberger-based geoelectric measuring procedure. The soil resistivity is determined by the water detector, which can also be used to detect underground hollows. The detector is capable of detecting underground water resources, such as freshwater, drinking water, gravel and ground water levels on the basis of the apparent resistivity of the ground.
GeoSeeker Mini operates the water and cavity detector
The GeoSeeker Mini water detector is controlled by a touchscreen. Choose the measuring depth and the quantity of scanning points and follow the graph. With images and icons that are easy to understand, the GeoSeeker Mini uses purely photo language for several languages.
In order to measure ground resistivity at certain places the electrodes have to be replaced several times. The color display allows you to read all instructions, where results are displayed after each scan. The final result is presented as a graphical 2D scan image at the very end of a measurement.
Water resources and cavity data visualization
The end result is calculated to generate a representative 2D scan image of subway resistivity following completion of geo-electric measurements. Users can read the diagram directly with the pictograms in the lower display area: The colors shown are deposits of water (blue with drops) and/or cavities detected in the scheme (red with tunnel symbol).
The display consists of multiple columns and provides the corresponding depth information, depending on the size and the depth of the measurement selected.
The user can switch to a simplified representation of measurement results with the left button (water drops) and the middle button (tunnel entrance).
The GeoSeeker Mini is language-independent, thanks to the implementation of step-by-step instructions and simple images and pictographs. This means that inexperienced users around the world can use the water detector – regardless of the language they speak.
GeoSeeker Mini geoelectric applications
In the detection of underground water resources and hidden cave sites, the geoelectrical detector OKM GeoSeeker Mini can be used. Because of its specific electrical resistivity features, both structures can be located.
Underground water resources have good electrical conductivity and their resistivity measure is low. The ability to detect water is extremely helpful
Dowsers, well builder water-finders, boiler companies
Agriculture, mining of fruit, contractors for construction
Water deposits can be detectable under surface
Fresh water, underground water supply, water veins underground water streams, headwaters
Detection of cavity
Hidden cavities and hollow areas have a rather low electrical conductivity and their resistivity is measured to produce high apparent resistivity. The cavity detection capability is helpful
