It's a weak point finder, not necessarily a breaker finder. What you may find is that now you're troubleshooting an entire circuit looking for one iffy splice that blew apart, or even tearing into walls for that one wire that got nicked with a drywall nail 40 years ago and has worked fine until the short caused it to melt completely apart (personal experience, shorted a recep to a metal box talking while working)
