OKM GeoSeeker

Description

Water and Void Detection up to a Depth of 250 m

Are you searching for groundwater resources or hidden voids up to 250 meters deep? The GeoSeeker is a professional geo-electric water and void detector that measures the ground’s resistivity and visualizes its scanning data in incredible 3D graphics. It is a highly mobile and user-friendly geo-electric detector designed and manufactured in Germany.

GeoSeeker uses a geo-electric measurement procedure based on Schlumberger to read the apparent ground resistivity. Based on this ground resistivity, the detector is capable of locating underground water deposits, gravel containing water, groundwater levels, as well as voids such as caves, tunnels, chambers, etc. Thus, the geophysical detector can be deployed both as a water detector and void detector.

Water Detection with GeoSeeker

The hardware components of the GeoSeeker are fully controlled by an Android tablet. All commands and measurement results are wirelessly transferred via Wi-Fi. With the pre-installed software application, you simply need to select one of the three supported scanning modes:

Active Scan (Precise)

In active scan mode, the GeoSeeker uses two electrodes to inject electrical energy into the underground soil. Two other electrodes measure the potential difference (voltage drop) at specific scanning points to calculate the final resistivity value.

This mode is used to detect underground water deposits, hidden caves, or even impermeable layers and barriers in the subsurface. In active scanning mode, you can set a specific depth range in which you will conduct your measurements. Thus, you will define a start and end depth ranging from 5 meters (16 feet) to 250 meters (820 feet).

Active Scan (Fast)

This scan mode is a rapid version of the precise scanning. It also injects electrical current into the subsurface and measures the potential difference (voltage drop) to calculate the soil resistivity.

Passive Scan

In passive scan mode, the GeoSeeker only uses two electrodes to read the natural voltage of the subsurface (no electrical energy is injected into the subsurface). This mode is used only for detecting common groundwater.

Analysis of Scans in the Application and in Visualizer 3D Studio

Once the measurement is completed, a 3D representation of the measured values is displayed on the tablet screen. Various color adjustment options help optimize the visualization of detected underground water deposits, gravel containing water, groundwater levels (in blue), as well as voids, caves, tunnels, chambers, or impermeable layers (in red).

Thanks to the major update of Visualizer 3D Studio in 2023, GeoSeeker measurements can now be displayed, optimized, and analyzed in more detail in the 3D software. The new 3D Volumetric Rendering view is a significant step for GeoSeeker users.
