Review on Easily Locate AC Circuit Breakers & Test GFCI Outlets with Klein Tools ET310 by Justin Sharp

I've long been a fan of small tools, although I don't own many. your hand tools. Screwdrivers, wire cutters and the like are always top notch. I see professionals use this brand the most. This circuit breaker finder is a handy tool although the sensitivity direction could be better. The receiver tends to start reporting the correct circuit about two points before and after the search. You have to slow down very much to make sure you are on the circuit that the transmitter is plugged into. Either way, it's still better than flipping multiple switches to find the right one. Also saves a lot of steps.
