R&D Since 1973 Stable Accurate Free upgrading at the original price after purchasing within six months The Single-Channel Cavity Detector utilizes natural electromagnetic fields as the working source to investigate subsurface electrical structures. By measuring electromagnetic responses across a wide frequency range at the surface, it exploits the principle of varying skin depths to reveal resistivity differences at different depths, accurately locating and characterizing underground cavities, disturbances, karst voids, and more. The ADMT Series 3D Imaging Cavity Detector is a leading professional-grade geophysical instrument for 3D imaging in archaeology and hazard assessment. It detects variations in subsurface resistivity caused by natural field strength changes to precisely determine the position, size, and depth of cavities, disturbed soil, and dissolution features. Widely used for leak detection in landfills, pre-construction void surveys, and disaster prevention, it
