Ground Scanner Equipped for Treasure Hunting in the Dark
The mountable flashlight allows treasure hunters to search for hidden artifacts and treasures with the eXp 4500 3D ground scanner even in the dark as well as in underground tunnels, bunkers and treasure chambers. In addition, obstacles in the scan field become visible in the bright light of the flashlight. This ensures that ground scans can be performed precisely and accurately and that correct measurement data can be generated.

Visualization of Treasure Finds and Discoveries
The sensors of the eXp 4500 are directly connected to the control unit which immediately displays the measurement data on the full color screen. These data can be stored in the internal memory of the device and can additionally be transferred to a computer.
On the computer, the specialized software Visualizer 3D allows to evaluate and compare all stored data. Furthermore, the user can determine depth, size and position of detected structures and objects.
