I searched, and found the thread on here about circuit seekers, but everyone mentioned on there was 500 dollars plus. I am not a contractor, but the shop I currently work for does not have a circuit seeker, and doesn't seem to be in a hurry to buy one. Lately, the type of work we're doing, it would be nice if I had one. I see all of these "breaker finders", which only work on energized circuits, on sale for 50 bucks or less. But I do need the ability to trace open circuits. Any suggestions?
