It works by transmitting an electromagnetic frequency through the conductive material of an underground utility. For water pipes, we would apply the signal directly to the pipe by connecting to the pipe at a riser, hydrant, or valve.

How does Magnetomatic pipe locator work?
To trace a pipe to its terminus, point the indicator in the direction the pipe is running and walk slowly. The tip will remain over the pipe. When the handle passes beyond the end of the pipe, the indicator will make a 180° turn and point backward toward the terminus.

How does a cable detector work?
To detect the magnetic fields emitted from a buried utility, the locator uses aerials built up of wire wrapped around ferrite rods. The aerials are used to amplify the small electromagnetic signals emitted by the utility and to provide an input to the locators' circuitry.May 23, 2017
