OKM FS-Thermoscan Metal Detector
Measuring Device Used to Detect Differences in Temperatures of the Environment

FS-Thermoscan is a measuring device to detect differences in temperatures of the environment. So it can identify cold and warm areas of a field and conclusions concerning hidden objects and structures are possible. FS-Thermoscan is usable as a stand-alone device or can be connected to the Earth Imager eXp 4000 and eXp 5000. In that way it is even possible to get 3d graphics out of the measure values.

The FS-Thermoscan stands up for its usage and compact design. Create high resolution 3d graphics of the underground by measuring the differences in temperature on the surface of the ground.

Possible applications are:

  • Measurement of Differences in Temperatures
  • Visualization of the Distribution of Temperatures
  • Detection of Cavities (caves, tunnels, chambers, chests, etc.)


  • Waterproof : No
  • Voltage : 12 VDC
  • Total Weight : 1.9 lbs (0.9 kgs)
  • Laser Range : Up to 164' (50m)
  • Laser Wavelength : 630 - 680nm

Factory Included Accessories:
  • Control Unit
  • Carrying Case
  • User’s Manual
  • External Power Supply with Charger and Cable (12V)

OKM FS-Thermoscan Metal Detector

FS-Thermoscan is a Measuring Device Used to
Detect Differences in Temperatures of the Environment

When the FS-Thermoscan is pointed at the side of the mountain, it can read the typical surface temperature. The trapped air in the cave keeps the mouth, even though covered over, slightly cooler and this difference can be detectable. Buried treasure (gold and silver) will absorb and store more heat than the ground surrounding it. As the ground cools, the treasure retains a higher degree of heat which is indicated on the meter of the FS-Thermoscan.

Use the FS-Thermoscan to locate physical treasures, caves, tunnels, mines, wells, etc. When the scanner is used at a treasure site at ground level, or scans the side of a hill, the scanner collects and focuses the energy onto the detection circuitry... By taking different readings of an area, the scanner will be able to determine temperature changes caused by buried metals, caves, mine shafts, etc.. Sometimes the ground is covered by heavy vegetation and it is almost impossible to take in larger metal detectors. In many cases the FS-Thermoscan would locate the hot spot or disturbed area, making it easier to locate the treasure. The FS-Thermoscan can be used ether as a stand-alone device or can be connected to the Earth Imager, EXP-4000 and EXP-5000 that allows the user to store and then download the readings through the 3D-graphics program provided with these units.

Because of the integrated laser pointer pinpointed measurements are possible. The device works contact-less and therefore a field can also be researched from far distances. This is an important advantage if the field is impassable by the searcher.
