Cavefinder is based on a geo-electric method which can be used to find cavities in the target area. At good ground conditions it penetrates up to 40m of depth. Handling of the locator is foolproof and only designed for detecting cavities such as caves, bunkers and sepulchers. With Version B the scanned area can furthermore be analyzed with a three-dimensional computer graphic. The evaluation of the measuring results take place on the spot. The display of the locator shows after a short time of calculation if there is a cavity or not.
