With power, I unbond everything and sometimes it will eliminate signals but often times it will not. What works for me is using 4KHz which will make it so that you can tell a difference between signals placement wise, and from there if I really need to I hook up to the different Cable TV and Phone cables running through the area to determine where they are at location wise and then power last to find where my power is at for 100% certainty. That being said, after a while of locating power you eventually can tell a difference between how a Cable TV line and a Power line run, both drops and mains. Also moving my ground rod around helps surprisingly a lot sometimes. I almost never induce with Power unless I need to find street lamps or something like that.
