3D ground scanner for treasure hunters and gold seekers

Are you tired of finding only small objects near the surface? Do you want to detect the real buried treasures which lie deeper than a normal metal detector can detect? OKM introduces the multifunctional sub-surface imaging detector and ground scanner eXp 4500. Developed for treasure hunters as well as prospectors, the eXp 4500 allows to find those buried treasures.

Unlike other ground scanners and imaging detectors, the eXp 4500 is truly unique. Calling the eXp 4500 a simple detector is not justified, due to its multitude of built-in functions, the eXp 4500 can locate buried items, ancient artifacts, lost treasures and naturally occurring mineralization like gold and silver at depths well beyond that of a common metal detector.

Measurement data in high resolution

The measurement unit of the eXp 4500 includes a PC-module with which data is displayed immediately on the full color screen. Measured data is stored in the internal memory and can be transferred later to a computer. Transferring measured values to a computer allows the operator to evaluate and compare all stored data. In doing this the operator can determine depth, size and position of targets using the professional Visualizer 3D software.
