Restoring a car and there is tons of wires I don't know where they go. This device found them all. Works very well for automotive needs. I tried another one for networking and didn't send a strong signal as this one did.
I originally bought this device to try and track a broken circuit to the circuit breaker in a mall for a doorbell. I did manage to track the signal to the room but could not find the breaker because of too much noise. however when I decided to give up and head back to remove the signal device I had discovered that some how the broken circuit somehow become unbroken.
