This is a good tool that is inexpensive and will pay for itself time and time again, chasing down open and short circuits just from the time you'll save as a flat-rate technician. I ordered it on Saturday, got it on Sunday, and used it on Monday. I was using another brand of short/open finder that you can buy off the tool truck for quite a few more bucks than this costs, and I've opened up the wire harness in four spots with false readings and found nothing. I spent a considerable amount of time trying to find an open circuit that could've been anywhere from the front PDC all the way to the spare tire where the Tire Pressure Monitor Module is, but decided to move onto something else because I had several things to do and come back to it later. I ordered this tool and used it Monday. I hooked it up to my circuit, and within 2 minutes I had located where the open was in the harness. I opened it up, and sure enough, that was where it was. I repaired the wire, and the Jeep was fixed. This tool shocked me, especially for how much I paid for it compared to other tools.

Bought this specifically to locate a break in a boundary wire for a Gardena robot mower (made by Husqvarna). I wasted hours trying to find it without a tool, but within 10 minutes of hooking this thing up, found the source of the break nearly 100 feet away from the loop. The signal had grown quite weak by then, but was still detectable if the sensor was placed next to the wire. I’m sure this thing will come in handy for future repairs to the boundary wire, as well as wiring issues on vehicles.It did include a pair of 9V batteries, but I think one of them died within a few minutes of use, so probably best to hand a new set on hand.

Used it it to find a short in my car. The one thing it doesn't tell you when you get it is that the box with wires has battery inside. The package that it came with only had 1 battery for receiver. I did not know you had to unscrew and open the box and there would be a battery inside that I needed to plug in. After that I could finally use it properly by using the sheet of instructions that it comes with. Its good to look for video that explain this better.

Excelente, solo falta un estuche para guardar

Doesn’t work well. If the vehicle or item you’re working on is metal you will pick up signal on everything.

The media could not be loaded. I picked this up after a suggestion from a friend, while trying to troubleshoot an intermittent open circuit to my SUV's HVAC blower. I suspected an issue with the wiring behind the dash, but it turned out to be in the fuse block under the back seat. Some of the plastic around the pin that was downstream from the fuse had melted, and caused a contact issue with the connector.There's no way I would have thought to look there, as previous troubleshooting steps verified voltage on both posts of the fuse. Using this device from the fuse side resulted in no signal on the underside of the fuse block, and along the wire bundle heading up to the front. Reversing the process and sending the signal from the HVAC connector end in the dash, gave a strong signal through the entire bundle all the way to the connector in the back, leading me to disassemble the fuse block and make the discovery.

The sensitivity of this thing is its main downfall. Have a melted/fried wire somewhere and it's now connected/shorted to the ground; which means just about everywhere in the vehicle is a continuation of said wire... the probe ends up giving it's tone anywhere inside the vehicle - as it'll pick up the tone from feet away - and you're always within a foot or two of something metal in a car.It's practically useless - unless you have a clean cut wire that's not shorting to anything (how often does that happen?). In this case I do think it's a "you get what you pay for" - I imagine the 300 dollar+ versions of this tool have the sensitivity dialed in.
