Imaging, GPR and two-box
3D ground scanners
Ground scanners record a grid of measurements and turn them into a picture of what is underground. They are used for caches, voids, tunnels, graves and large buried objects rather than single coins. Options run from the compact GroundTech GR-4 to OKM's multi-sensor eXp 5500 and the Gepard ground penetrating radar. Depth figures are the makers' own and depend on target size and soil.
