The OKM GeoSeeker Groundwater and Cavity Detector measures apparent resistivity and displays 3D survey data on an Android tablet. A groundwater detector or cavity detector image requires geological interpretation and independent checks before drilling or excavation.
OKM GeoSeeker Groundwater and Cavity Detector
The OKM GeoSeeker Groundwater and Cavity Detector is offered with product guidance and setup support. A groundwater detector survey should be planned for local geology, and a cavity detector indication needs independent confirmation.
Groundwater and Cavity Detector Survey Method
The OKM GeoSeeker Groundwater and Cavity Detector measures apparent soil resistivity with electrodes. This groundwater detector can highlight conductive zones and possible void responses, but a cavity detector image does not prove a particular underground structure.
Groundwater and Cavity Detector Scan Modes
The OKM GeoSeeker Groundwater and Cavity Detector is operated from a supplied Android tablet in the listed configuration. The groundwater detector offers accurate active, quick active and passive scan options; a cavity detector result still requires suitable survey design.
The OKM GeoSeeker Groundwater and Cavity Detector uses electrode measurements to estimate resistivity in active scan mode. This groundwater detector or cavity detector reading is an interpreted estimate, not an exact depth guarantee.
This mode scans the ground faster. It shortens the measurement time. So, you can scan large areas quickly. It still uses current injection. This ensures the data remains accurate.
This mode does not inject current. Instead, it measures natural voltage. Use this mode if there is electrical interference. It is also perfect for silent scans.
The OKM GeoSeeker Groundwater and Cavity Detector can highlight low-resistivity zones that may contain water. A groundwater detector indication must be checked against geology and drilling; a cavity detector image cannot establish water quality.
High resistance often means hollow spaces. The device maps these hidden rooms. It finds old cellars and bunkers. You can see them in 3D. The software uses Red and Blue colors.
OKM cites customer finds down to 250 metres for the OKM GeoSeeker Groundwater and Cavity Detector. This groundwater detector maximum is not guaranteed at a given site, and cavity detector depth also depends on geology and survey setup.
Groundwater and Cavity Detector Wireless Operation
The OKM GeoSeeker Groundwater and Cavity Detector sends commands and readings wirelessly between its controller and tablet. This groundwater detector uses Wi-Fi for measurement data; a cavity detector survey should keep the electrode layout and site notes recorded.

The OKM GeoSeeker Groundwater and Cavity Detector app guides the operator through electrode spacing and scan setup. A groundwater detector image should be compared with local borehole evidence, while a cavity detector interpretation needs an independent method.
Groundwater and Cavity Detector Interpretation
Groundwater and Cavity Detector Target Analysis
The OKM GeoSeeker Groundwater and Cavity Detector interprets measured resistivity contrasts. A groundwater detector display may suggest conductive layers, and a cavity detector display may suggest resistive zones; neither image identifies an exact target alone.
Possible groundwater layers and possible cavities are the principal targets of the OKM GeoSeeker Groundwater and Cavity Detector. The groundwater detector cannot establish water quality or sustainable yield, and a cavity detector result should be verified before excavation.
- Good Conductors (Blue): These have low resistance. This means Water. Examples are freshwater or aquifers.
- Poor Conductors (Red): These have high resistance. This means Cavities. Examples are tunnels, rooms, or bunkers.
- Medium Conductors (Green): This means normal soil. It could be loam or sand.
Groundwater and Cavity Detector 3D Views
The OKM GeoSeeker Groundwater and Cavity Detector renders measured values in 3D on the tablet. This groundwater detector visualization is an analysis aid; a cavity detector color map is not direct proof of a tunnel or room.
