Grailfinder

The Grailfinder is a cavity detector combining geo-electric and electromagnetic pulse methods. It allows to localize cavities, tunnels and caves in the underground.

All of our metal detectors and geophysical detecting instruments are part of the FS – Future Series, a line of our latest technology to detect buried objects and underground structures. A detailed analysis of the measured results is possible through our 3D software Standard 3D and Visualizer 3D.

We don’t manufacture this product anymore. For cavity detection consider Gepard GPR 3D or our cavity detectors.
