Induction gives you a way of getting a signal onto a line when a direct connection isn’t possible or doesn’t give you the result you want.

Benefits of Induction:
1. Energize a conductor without physically touching it.

2. With proper transmitter management (placement, orientation, aiming, frequency selection, power output) you can determine which conductor gets the most signal and creates the best locating circuit. Induction may, in some cases, help isolate difficult (congested) circuits.

3. Induction can be used to sweep an area to see if any conductors are present. If the likely direction of the pipe or cable is known, two people can sweep, with one carrying the transmitter and one carrying the receiver, as they walk in tandem. If the receiver and the transmitter cross an underground conductor at the same time it may be energized and show up on the receiver.
