The Gepard GPR 3D from OKM is a highly flexible and powerful ground penetrating radar for detecting underground objects such as pipelines, cavities, cables, ducts, tunnels, bunkers and foundations. This ground penetrating radar uses an unshielded, multi-directional transmission system to reach maximum depths of up to 40 metres (131 ft).
 The compact unit can be easily operated by a single user via an Android tablet . The device's radar sends a signal into the ground and waits for the signal to reflect or echo to detect anomalies beneath the surface.
