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 finding 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.

Characteristics Of The EXP 4500


  • Lightweight portability
  • Non-intrusive real-time ground surveying
  • Quick and easy setup and operation
  • Live color-coded surveys
  • Allows for impromptu and fast surveys
  • Immediate on-site interpretation of target area
  • Measured values showing extreme depth of survey
  • Measured values showing the location of targets within the surveyed area
  • Highly sensitive and accurate metal detecting device

Applications Of The EXP 4500 Ground Scanner


The EXP 4500 ground scanner is a high-performance metal detecting device which is specially designed for the following applications:

  • Archaeological 3D surveys, metal detection, treasure hunting, and gold prospection
  • Pinpointer function in locating the exact position of buried treasures and artifacts
  • 3D imaging including size and depth
  • Detecting gold and other items of great value
  • Finding ancient artifacts, hidden treasures, gold, silver, bronze, hoards of coins, treasure deposits, pirate chests
  • Tunnels, voids, and cavern locating
  • Mineral and natural gold prospecting

With several specialized detection antennas, the EXP 4500 ground scanner can also be used in highly mineralized areas for treasure hunting and prospecting.

Special Probes And Antennas


The functionality of the EXP 4500 metal detector is only one key point that makes it a unique treasure hunting unit. Every single probe and antenna is tuned and optimized for its own purpose and function. The following antennas are available:

  • GPR-Antenna (25cm, 50cm, 75cm, 100cm)
  • Antenna for tunnel detection
  • Super Sensor for high-resolution ground scans, pinpointing and mineral detection

Operating Modes Of The EXP 4500 Ground Scanner And Metal Detector


Hidden artifacts are of different sizes and made from different materials. So the treasure hunter needs different operating modes and locating methods to find all of those hidden treasures at various depths under the ground surface. The EXP 4500 ground scanner is capable of the following operating modes:

  • Ground Scan is ideal for treasure hunters and archaeologists looking for underground artifacts, treasures as well as historical and archaeological items
  • Mineral Scan has been integrated for gold prospectors, seekers, and miners, who are looking for natural gold and minerals
  • Tunnel Scan is a specialized mode to detect underground voids, tunnels, cavities, and hollow spaces
  • PinPointer assists you in locating the correct position of detected items
  • A magnetometer is helpful to locate ferrous metals like iron and steel
