Klein Tools ET450 Advanced Circuit Breaker Finder and Wire Tracer Kit for Energized and Non-Energized Breakers, Fuses, and Wires

This is well built, durable and worth every penny. Connections are solid and well thought out. It is a Klein so I expected it to be good BUT, for the price point, better then I expected.Attached pictures are of a valve, you really have to look close, that was buried under 12 inches of rock and 18 inches of very compacted soil root and rock. The valve was well over 500 ft away from the controller. I didnt walk right to it, took a lot of effort but found it. Valve is over 25 years old and the person who did the landscape needs a good talking too!!!!

Great purchase. I used it to track broken irrigation wires, the power, and common wire were broken in several places after my lawn client had a pool built. It worked perfectly even with the wires being +12” under ground. I found the break in the wires within 5 minutes. Would definitely buy again or recommend if you need to trace irrigation wires, broken or unbroken. The carrying case is also nice and durable, and it came with batteries for both devices.

Works better than I expected for tracing wires through walls, floors, and even under a gravel drive. Following the instructions, I connected the ground lead of the transmitter to a good and certain ground; the one I used was several feet away from the unpowered type NM cable I wanted to trace. The transmitter red lead was clipped to one of the NM wires. The receiver traced the cable down the wall, underneath the floor for 50 feet, then up the wall to a junction box. It was necessary to adjust the sensitivity along the way, and I found it best to watch the numbers for best accuracy.The best thing was using the Klein ET450 the next day to trace an underground communication cable from a basement to an outbuilding about 60 feet away; we estimate that it is buried about 2 feet down. I was not expecting the ET450 to work, but wanted to give it a go. The same procedure was followed by connecting the transmitter to a solid ground a few feet away from the cable, and clipping the red lead to one of the wires in the bundle. Going outside with the receiver, it picked up the signal at a medium high sensitivity setting. Watching the numbers I could find the peak signal location within just a couple of inches and mark that. The whole path was traced to the outbuilding.The sound indication is good for giving a general indication of the wire you are locating, and the sensitivity level is necessary to be adjusted to narrow down the location to a few feet. Watching the numbers on the display will let you see very fine level changes to localize to a few inches.

I used this to locate a dead well wire roughly 500 feet with just the power from the instrument. I was very impressed with its capability.

I like the sensitivity control and so far it works wellNot sure how it works underground, but it traces romex in the wall very well.

Simple to use and works outstanding, paid for itself the very first time I used it. Every Electrical Contractor should have one of these.

This is a great tool!! intuitive setup and use. sensitivity adjustments work well for determining general direction and pinpointing location. the only thing that is different is that some on the batteries in the transmitter are mounted in the case and some are in the cover, which is less than obvious. read the instruction completely to determine how many batteries are needed.

Good quality kit. Works well.
