                So far this has proven to ge a great tool. As a home owner often something electrical must be repaired, and I really hate being shocked. With this tool locating the correct circut breaker is simple, and it can be done alone, and not two people trying to coordinate via cell phone when the correct breaker is located. In my opinion, this is a mandatory home owner must have tool.

                      Klein circuit locate finder
                      Not being a knowing of electricity very well, it was easy to use. I attach the transmitter to outlet, bulb or socket and you bring the receiver to the fuse panel and it detects what fuse belongs to it and if it’s wired correctly.

                      Very easy to use to identify electrical circuits in you home or small business. etc. Able to check light bulb circuits, new add-on circuits, existing circuits back to the Circuit Breaker panels. The portion that plugs into the socket is also a trouble shooting tool to check for mis-wired circuits, also checks Ground fault receptacles for proper operational tests. As well as open circuits. Truly multi-functional and the soccer tester is safely stored in the end of the hand tester that turns red when the circuit is identified. Green for normal. When checking your breakers be sure to follow the instructions and go through the panel twice before you do your final test sd the first test can give you a false reading. High Quality tool, as all Kiein tools are.

                      The Klein tools circut breaker finder is a huge time saver. My electricial circits were not marked in my panel, so when doing projects before this tool, I would have to leave a light on or plug in radio in, and flip all breakers untell the one I wanted shut off. This is not quick or easy to re set all the clocks I just turned off. What this tool, you simply plug transmitter I, and scan the breakers on the service panel to find correct circut. The transmitter with lights also shuts off when power, showing positively that the power to that curcut is off. If you do electricial work, this tool will help you find curcuts quickly. You will mot be disappointed.
