10. Circuit Breaker Finder: No More Guesswork

Ever had to flip breakers one by one, hoping you'd find the right one? A circuit breaker finder takes out the guesswork. It helps you quickly identify which breaker controls the circuit you're working on, so you can safely turn it off before getting started.

Here's how it works: the tool comes with two parts --- a sending unit and a receiving unit. Plug the sender into a live outlet, then use the receiver at the breaker panel. It scans the breakers, and when it finds the right one, a light flashes, and you'll hear a beep.
