No electrical ground present? Have a helper hold the other lead from the tone generator.
Completely true, but since you can carry a ground around with you in an extension cord, there's no need to do this.
Works better IMO.
That's not true. It works, but not better. It's important to know that this works, though, because the things a toner can do are not at all intuitive.
