SL-205-type underground cable detectors can not be excavated in the case of complex earth, convenient and accurate detection of underground communication cables, power cables to the direction of buried depth of soil. Is the power, communications sector and industrial enterprises indispensable equipment And the right-hand helper, by sending a specific electromagnetic wave signal to the underground pipeline, the probe using the probe perpendicular to the ground plane tangent to the magnetic field lines, the received signal is small (almost zero) to determine the principle of the direction and depth of the buried cable.
