OKM GeoSeeker Professional Underground Water Detector & Cave Locator - Find Water Sources, Minerals, and Cavities for Exploration, Survival, and Outdoor Adventures

GeoSeeker Underground Water and Cavefinder by OKM

Highlights

• Geoelectric water and cavity detector: Determines ground resistance up to a depth of 250m (820ft) and visualizes the measured values in 3D
• Depth: Customers found water up to 250 meters – check our references
• Use cases: Water detection, cavity detection, geotechnical engineering
• Operating modes: Geoelectrical scan
• Detectable objects: Water deposits, water-bearing gravel, cavities

The OKM GeoSeeker Water and Cavefinder is the most accurate and deepest detection Ground penetration locator OKM has ever created. The GeoSeeker in Active Scan modes can output a large scan voltage of up to 390 Volts. The active scan mode constitutes an extremely accurate scan method and will provide you with the very best results when locating water and caves or caverns.

The Geoseeker can also operate in a passive scan mode without requiring direct power input in which case it will only measure the naturally occurring voltage that is in the ground itself. This type of scan is suitable in sloping areas with an underground watercourse. The GeoSeeker can easily make accurate 3D graphic scans of underground resistivity at a maximum depth of up to 820 feet or 250 meters. Easy to follow step-by-step guided measurements and wireless data transfer to the Tablet PC make using this highly sophisticated geo-electrical detector one of the deepest and easiest to use!

The OKM GeoSeeker is a professional geoelectric water and cavity detector that measures soil resistivity and displays your scanning data in incredible 3D graphics. It is extremely mobile and easy to operate; this geoelectric detector is designed and manufactured in Germany.

The GeoSeeker uses a geoelectrical measurement procedure based on the Schlumberger method to read soil resistivity. Based on this ground resistance, the detector is able to locate groundwater reservoirs, gravel, and groundwater level as well as cavities, caves, tunnels. Therefore, the geophysical detector can be deployed as both a water and a cavity detector.

The hardware components of the GeoSeeker are completely controlled by a modern Android tablet. All commands and measurement results are transferred wirelessly over Wi-Fi. Using the pre-installed software application, simply select one of the three compatible scanning modes:

Active (precise) scanning

While using this scanning mode, the GeoSeeker uses two electrodes to inject electrical energy into the underground ground. Two additional electrodes measure the potential difference (voltage drop) at specific scanning points to calculate the final resistivity value. This mode is used to detect groundwater deposits, hidden caves, or even impermeable layers and barriers within the groundwater. In active scans, you can define a specific depth range in which you are going to perform your measurement. So, you will define an initial and final depth between 5 meters (16 feet) and 250 meters (820 feet).

Active scan (fast)

This scanning mode is a fast version of accurate scanning. It also injects electric current into the subsoil and measures the potential difference (voltage drop) to calculate soil resistance.

Passive scanning

While using this scanning mode, the GeoSeeker uses only two electrodes to read the natural subway voltage (no power is injected into the subway). This mode is used to detect only water flowing underground.

The GeoSeeker water detector graphical user interface is available in the following languages:

Deutsch, English, Français, Spanish, Italian, عربي, Λληνικά, Türkçe, 中文, Pусский, Nederlands, فارسی.

GeoSeeker provides simple step-by-step instructions to help you complete the measurement. Simply follow the illustrated instructions until your measurement is complete. After the measurement is complete, a 3D graphical representation of the measured values is created and displayed on your Tablet PC screen. Some color adjustment options are provided to optimize the 3D graphical display of your underground water, gravel, and groundwater level (shown in bluish colors), as well as cavities, caves, tunnels, chambers, or waterproof layers (shown in reddish colors).
