eXp 4000
Available in Basic and Pro Version
Due to the use of advanced technology this is the Mercedes of under the earth imaging instruments.


Results to 80 Feet!

The eXp 4000 is the successor of the eXp 3000. Advanced technology allows measurements in brilliant resolutions up to depth of 25m (Over 80 feet). The handling is easy and possible without the need of a laptop. The measurement unit of the eXp 4000 includes a pc-module where the data will be displayed immediately on the color screen. All measured data will be stored in the internal memory and can be transferred to a normal computer to evaluate and determine depth, size and position of targets with our optional software Visualizer 3D.

The eXp 4000 has many different functions especially for treasure hunters. So it has:

  • Distinction of metals and cavity
  • Easy handling and compact equipment
  • No laptop is needed for working


  • OKM - MODEL EXP LOCATES GOLD BARS IN GREECE

    World War II Gold Bars recovered after 60 years hidden in the ground, millions more still to be found.

    During WWII allies sent gold coins and bars to European Guerilla fighters holding out against Axis occupiers. Gold was used to buy arms, explosives and bribes to assist Guerillas. Large amounts of gold were secretly buried so it would not be found during raids. Entire Guerilla bands were killed leaving huge gold hoards waiting to be found. OKM ground penetrators prove to be successful in locating buried gold.

    2 Sensors for 2 times the resolution are built into each
    eXp 4000 GPR antenna!


    3D Software, optional with basic, included with Pro Version

    To ease the work with eXp 4000 and the subsequently image evaluation the following functionality was integrated:

  • Automatic display of object differentiation
  • Automatic signal stabilization during measurement
  • Automatic antenna identification




  • Above is an acoustical signal in real time of metal target shown in yellow on the monitor of the exp4000 while in the metal detector mode. (Optional DDV system [Disc Detector Visualization system required])

    The comprehensive equipment of the eXp 4000 is only one point that makes it a unique treasure hunting unit. Every single probe was optimized for its own purpose. So you can work with the following antennas:

    Additional Options:

  • GPR-Antenna ( 25cm, 50cm, 75cm, 100cm )
  • Antenna for metal discrimination ( DDV-System )
  • Antenna for tunnel finding
  • Super Sensor for high resolution ground scans
  • With a weight of only 1500g the eXp 4000 is ideal for fast searching an area. The integrated color monitor is also usable for night searching. But also in the sunlight the display is very clear in contrast to a laptop.
