Abstract
A dynamic magnetic locator includes a linking mechanism linked with a first sensor to horizontal move or rotate the first sensor; a second sensor horizontally arranged beside the first sensor; a third sensor vertically arranged atop the second sensor; and a control module connected to the sensors and receiving magnetic signals of the underground metal pipe. The control module controls the linking mechanism to horizontal move or to rotate the first sensor to obtain a plurality of magnetic signals. The control module processes the magnetic signals to obtain a position and a depth of an underground metal pipe.
