Abstract
A computer-integrated survey system which is useful in the location of underground obstacles, such as rocks, concrete, steel and ice is disclosed. Specifically, the detection system of the present invention is operated by a microcomputer, having a series of sensors, which integrate position-determining systems, time, sub-surface radar, sonar, seismograph, laser equipment and earth-resistivity functions to accomplish its stated purpose. The system is specially designed in a compact fashion so that it may easily be hand-held, if so desired. Simultaneous with the detection and measurement of underground obstacles, in a preferred embodiment of the present invention, a permanent record of all information may be constructed for subsequent review and print-out.
