Cable Drum with Pipe and cable locators require a complete circuit to have a detectable signal on the pipe. In most situations, the signal travels from your transmitter down the pipe and travels back to the grounding rod to complete the circuit. When there is another parallel metallic line, it can also travel back through that line if there is less resistance putting a signal on the line you don't want to locate. At times the ground may not carry the signal back to the grounding rod very well, particularly in dry sandy soil.
To have a cleaner locate In both of thee above cases, you can make your own completed circuit without using the actual earth, by running a wire from the end of your intended locate back to your transmitter. This helps keep form accidentally locating the wrong line when it returns down the other pipe or cable. With the cable drum wire, you know exactly where the signal is traveling back. It can also insure you have a good circuit when the actual ground electrically resistant.
