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:

		accoustical 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.
