OKM GrailfinderExploration of tunnels and caves

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
