OKM GeoSeeker

Water and Void Detection down to 250 m (820 ft) Depth

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 geoelectrical detector designed and manufactured in Germany.

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 to locate underground water deposits, water-bearing gravel and groundwater level as well as cavities like caves, tunnels, chambers and the like. Thus, the geophysical detector can be deployed as water finder or cavity detector at the same time.

Water Detection with GeoSeeker

GeoSeeker hardware components are completely controlled by a modern Android Tablet PC. All commands and measurement results are transferred wireless via Wi-Fi. Using the pre-installed software application, you simply select one of three supported scan modes:

Configure and Conduct Scans via GeoSeeker App

The GeoSeeker application for Android provides simple step-by-step instructions to assist you in completing the measurement. You simply follow these pictured instructions until your measurement has been finished.

Analyze Scans in the App and in Visualizer 3D Studio

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.
