3D Scanner OKM eXp 4500




OKM eXp 4500

The OKM eXp 4500 is a multifunctional, sub-surface imaging detector and ground scanner that detects the real buried treasures which lie deeper than a normal detector can detect.

The eXp 4500 is built for treasure hunters as well as prospectors who want to find those buried treasures.

Due to multitude of built in functions, the OKM eXp 4500 can locate buried objects, ancient artefacts, lost treasures and even naturally occurring mineralization like gold and silver at depths, far beyond what a normal metal detector can reach.

Characteristics and applications of the eXp 4500 ground scanner

The eXp 4500 3D ground scanner is a powerful device designed for a variety of applications:

  • Archaeological 3D surveys, metal detection, treasure hunting and gold prospection
  • pin pointer function to 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

By using several specialized detection probes, the eXp 4500 ground scanner can also be used in highly mineralized areas for treasure hunting and prospecting.

The versatility of the eXp 4500 lies in the large number of available measuring probes, which are each optimized for their respective field of application.

Available probes:

  • GPR probe (25 cm, 50 cm, 75 cm, 100 cm)
  • Probe for tunnel and cavity location
    • Supersonic probe for high-resolution ground scans, pin pointer and mineral detection
    •      FS thermal scan for thermal images in 3D

The measurement unit of the eXp 4500 also includes a PC module with which the measurement data is immediately displayed on the color display of the monitor. As a result, no laptop is needed during the measuring process. The measurement image can be viewed directly on the screen, stored in the integrated memory and can be transferred to a computer in brilliant resolution later. By means of the software Vizualizer 3D the depth, the size and the exact position of the buried find can be accurately determined.

Advantages of the eXp 4500 compared to other ground scanners:

  • lightweight portability
  • non-intrusive real time ground surveying
  • quick and easy set up 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 location of targets within surveyed area
  • highly sensitive and accurate metal detecting device

Technical certificates and 2 years of warranty are standard for all OKM metal detectors. Extensive field tests ensure the high quality of all OKM ground scanners which leave the OKM factory.

Operating modes of the exp 4500 ground scanner and metal detector

  • 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
  • Pin Pointer assists you in locating the correct position of detected items
  • Thermo Graph and Thermo Scan are used to detect cavities and underground tunnels by measuring differences in temperature
  • Magnetometer is helpful to locate ferrous metals like iron and steel
