FS-Thermoscan is a thermography and cavity detector to localize differences in temperatures of the environment. Thus, it can identify cold and warm areas of a field and allows to draw conclusions about hidden objects and structures.

We don’t produce this product anymore. We recommend our current cavity detectors as replacement.
