Metal detector eXp 3000 - Treasure hunting equipment

The Earth Imager are the stars of our "FS - Future Serie". They can represent graphical measuring results without using any additional computer. Because of the high amount of optional accessories they are extendable individually. Every customer can purchase only that what he needs for his purposes.

The Earth Imager eXp 3000 is not manufactured anymore and not longer available. The device has been replaced by eXp 4000 which is more optimized and powerful.

The eXp 3000 is the Mercedes under the earth imaging instruments. Advanced technology allows measurements in brillant resolutions up to very high depths. The Handling is absolutely easy and possible without the need of a laptop. The measurement unit of the eXp 3000 includes a pc-module which what the data will be displayed immediately on the color screen. All measured data will be stored in the internal memory and can be transfered to a normal computer to evaluate and determine depth, size and position of targets with our software Visualizer 3D.

The metal detector for treasure hunting eXp 3000 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

To ease the work with eXp 3000 and the subsequently image evaluation the following functionality was integrated:

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

The comprehensive equipment of the treasure detector eXp 3000 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:

  • GPR-Antenna (25 cm, 50 cm, 75 cm, 100 cm)
  • Antenna for metal discrimination (PI, pulse induction)
  • Antenna for tunnel and void finding
  • Super Sensor for high resolution ground scans

With a weight of only 1400 g the eXp 3000 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.

Here we present you some discoveries, which has been located with this geophysical metal detecting instrument. If you also made a discovery or know somebody who made a fantastic finding with our metal detectors, just write us an email or use our online form!

16 kg coins detected with OKM metal detector in Maghreb area

16 kg coins detected with OKM metal detector in Maghreb area

One of our customers from Maghreb in North Africa reported about his successful treasure hunt. He was using the 3d metal detector and ground scanner eXp 3000, the predecessor of the earth imager eXp 4000, when he located some anomalies inside the underground. The customer was searching in very uneven ground and therefor he used the 25 cm GPR probe of his geophysical phase reader to obtain accurate detecting results.


Unexpected discovery in Saudi Arabia

Unexpected discovery in Saudi Arabia

A customer from Saudi Arabia informed us about his beautiful discovery. The treasure has been located by the metal detecting instrument eXp 3000 - the former model of eXp 4000. The treasure seeker informed us about the following discoveries, which has been made: a gold statue, a Nofretete statue and a Pharao statue. There are still lots of hidden treasures which wait to be discovered in Saudi Arabia and other Middle East countries.


eXp 3000 discovered bullions of the guerillas

eXp 3000 discovered bullions of the guerillas

In november 2005 some of our customers found a wooden chest filled up with gold bars. Those bullions were buried during the World War II by greek guerillas. The treasure hunters and archeologists used different metal detectors and geophysical instruments like the Earth Imager eXp 3000, the predecessor of eXp 4000.


Earth Imager eXp 3000 detects ancient dagger

Earth Imager eXp 3000 detects ancient dagger

This ancient dagger from the early middle age was found in a depth of 60 cm. After unsuccessful searches with different other metal detectors the dagger has been detected with the basic equipment of the Earth Imager eXp 3000. Only the iron blade kept well preserved over all the long time the object was buried in the ground. There is only a small piece left which belongs to the wooden handle of the dagger. The exact place of this discovery is undisclosed.
