OKM Gepard GPR

Ground Penetrating Radar with Android Tablet PC

The Gepard GPR is a very flexible, transportable and powerful ground penetrating radar for detecting underground items like pipelines, cavities, cables, conduits, tunnels, bunkers, foundations and the like.

The Gepard ground penetrating radar uses an omnidirectional unshielded transmission system to reach maximum depths up to 40 meters deep. This light, agile and compact unit can be easily operated by a single operator.

The RADAR (Radio Detection and Ranging) sends a signal into the ground and awaits the reflection or echo of the signal to detect sub-surface anomalies, like the following:

  • Underground walls, basements and concrete reinforcements
  • Hidden cavities, graves and sepulchers
  • Water level and underground rivers and aquifers
  • Buried pipelines, conduits and cable harnesses
  • Backfilled wells, galleries, trenches and dugouts
  • Septic tanks, distribution boxes and drainage pipes
  • Secret tunnels, bunkers and shelters
  • Buried treasure chests, statues and caches

The Gepard ground penetrating radar is using a multiple transmission frequency range starting at 60 MHz up to 300 MHz which is realized by adjustable telescopic antennas. It furthermore supports many automatic adjustments to optimize your ground surveys on specific soil types, which makes the handling of the Gepard ground radar very easy. You just set your depth resolution and start surveying.


The OKM on-site trainer is operating the Gepard GPR in a gold mine in California, USA.

The measured data of the ground penetrating radar is directly transferred to an Android Tablet PC. The Android software receives the data via Bluetooth and displays it immediately on screen.

The software has the capability of integrating a GPS signal, Google Maps, automatic filtering and entering notes for later recollection of specific scan details. Additionally, automatic filtering capabilities are useful to improve the results of your scan and find hidden objects and structures more easily. Due to the integrated GPS all scan positions can be stored along with the scan data.

The Android software applications is available in the following languages:

  • English, Français, Deutsch, Español, Ελληνικά, Italiano, فارسی, 中文
