If you are looking for water resources or hidden cavities up to depths of up to 250m (820ft), the OKM GeoSeeker is the device of choice.
The OKM GeoSeeker is a professional, geoelectrical water and cavity detector, which detects cavities and water deposits by measuring the resistance of the soil and visualizes them in sensational 3D graphics. The GeoSeeker is a mobile, easy to operate geoelectrical detector, designed and manufactured in Germany.
The measurement procedure used by the GeoSeeker is based on the Schlumberger method to read the soil resistivity. Based on the soil resistance, the detector is able to detect underground water resources, aquifers and groundwater levels as well as e.g. cavities, caves, tunnels, chambers.
The electronic components of the GeoSeeker are completely controlled by a modern Android Tablet PC. All commands and measurement results are transmitted to the Tablet PC via WiFi. The pre-installed software application provides the following measurement methods.
While using this scan mode the 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).
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 resistance of the soil.
While using this 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.
The GeoSeeker software application guides the user step-by-step through the complete measuring process. You simply follow these visual instructions until the measurement has been finished. After completing the measurement, a graphical 3d representation of the measure values is created and displayed on the screen of your Tablet PC. Some color adjustment options are provided to optimize the graphical 3d visualization of your underground water deposits, water bearing gravel and groundwater level. (displayed in bluish colors) as well as cavities, caves, tunnels chambers or impervious layers (displayed in reddish colors).
The measuring electronics of the OKM GeoSeeker are built-in into a waterproof and impact-resistant Peli-Case, which ensures that your equipment is always well protected and ready for transportation.
