Grailfinder - Exploration of tunnels and caves

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. Beside the measuring instruments it includes our 3D software which assures a detailed analysis of the measured results.

The Grailfinder is a metal detector with integrated geoelectric.

The Grailfinder is a combined device including geo-electric and electromagnetic pulse method. It combines the functionalities of Rover C and Cavefinder, so that the device includes the following functionalities:

  • Acoustical magnetometer
  • Graphical ground scans (manual/automatic)
  • Automatic cavity measurement with easy "Yes/No" evaluation
  • Graphical control output to a computer

The Grailfinder includes a magnetometer to locate ferromagnetic metals like iron, nickel and cobalt which are situated near to the surface. With the standard probe or the optional available Super Sensor graphical measurements can be made and evaluated and analysed in the 3D software.

Because of the integrated microprocessor technology ground balance, depth measurement and data storage will be performed automatically by the device. The evaluation of the measured data takes place at the computer where the scanned area can be analyzed in a three-dimensional graphic with the help of the 3D software.

Here we present some relevant discoveries, which have been located. If you also made a discovery or know somebody who made a fantastic find with our metal detectors, just write us an email or use our online form!

An ancient wine cellar has been located on an old french castle by using the geophysical instrument Grailfinder. This old cave which is estimated from the 15th century by experts and so has an unexpected high historical value, has been located in a depth of 21 meters. Planete Detection IDS has led this professional underground research and located the entrance of this void. By presence of the first french channel TF1 they demonstrated the metal detector Grailfinder, found the cellar and finally went down with the cameramen and discovered 4 big rooms. "It was just wonderful!" so IDS.
