Water and Void Detection down to 250 m (820 ft) Depth
Are you looking for underground water resources or hidden cavities up to depths of 250 meters (820 ft)? GeoSeeker is a professional geoelectrical water detector and cavity detector that measures the ground resistivity and visualizes its scan data in incredible 3D graphics. It is a very mobile and easy to operate geoelectrical detector designed and manufactured in Germany.

Water detection in Africa
Water detector OKM GeoSeeker was handed over in December 2017 to "Aktion Pro Afrika" - a nonprofit organization - and already provides successful measurement results during the search for underground ...
GeoSeeker utilizes a geoelectrical measurement procedure based on Schlumberger to read the apparent resistivity of the ground. Based on that ground resistivity 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.
GeoSeeker hardware components are completely controlled by a modern Android Tablet PC. All commands and measurement results are transferred wireless via Wi-Fi. Using the pre-installed software application, you simply select one of three supported scan modes:
Active Scan (Accurate)
In the Active Scan mode, GeoSeeker utilizes two electrodes to inject electrical power into the underground soil. Two additional electrodes are measuring the potential difference (fall of voltage) at specific scan points to calculate the final resistivity value.
This mode is used to detect underground water deposits, hidden caves or even impervious layers and barriers within the underground soil. In active scans, you will be able to define a specific depth range in that you are going to conduct your measurement. So you will define a starting and ending depth between 5 meters (16 feet) and 250 meters (820 feet).
Active Scan (Quick)
This scan mode is a quick version of the Accurate Scan. It is also injecting electrical current into the underground and measuring the potential difference (fall of voltage) to calculate the resistivity of the ground.
In the Passive Scan mode, the GeoSeeker only utilizes two electrodes to read the natural occurring voltage of the underground (no electrical power is injected into the underground). This mode is used to detect underground flowing water only.
Configure and Conduct Scans via GeoSeeker App
The GeoSeeker application for Android provides simple step-by-step instructions to assist you in completing the measurement. You simply follow these pictured instructions until your measurement has been finished.
Analyze Scans in the App and in Visualizer 3D Studio
After completing the measurement, a 3D representation of the measured values is displayed on the tablet screen. Various color adjustment options allow optimizing the visualization of detected underground water deposits, water-bearing gravel and groundwater level (shown in blue) as well as cavities, caves, tunnels, chambers or impervious layers (shown in reddish colors).
Thanks to the major update of Visualizer 3D Studio in 2023, GeoSeeker measurements can now also be displayed, optimized and analyzed in greater detail in the 3D software. The new render view Volumetric 3D is a major milestone for GeoSeeker users.
