    OKM GeoSeeker Water Detector - 820ft

    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. 

    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 of locating underground water deposits, water-bearing gravel, and groundwater levels as well as cavities like caves, tunnels, and chambers. 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 wirelessly 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 measures 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 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 currents into the underground and measuring the potential difference (fall of voltage) to calculate the resistivity of the ground.

    Passive Scan

    • 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.

    Analyze Scans in the App and in the 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).

    Easy-to-transport Water Detector

    • The GeoSeeker hardware is integrated in a waterproof and shock-resistance Protector case. Thus, your geoelectrical equipment is well-packed and always ready for transportation.
