Tracks wires through walls and tiles.
It works quite well. I was able to trace a dead wire to a switch behind drywall and ceramic tiles. It took me much longer to read the instructions than to find the problem. Once you understand how it works in principle it is a wonderful tool. You can trace any dead wire through walls and stone. Saved me from paying an electrician just to come out and point me to a defective ghost switch.

Try this before calling an electrician.
Great tool, I am not an electrical expert, but I have done my fair share of electrical work. I got stumped trying to find the source of a light switch and this helped me track it back to an outlet that should not have been on a light circuit. Would not have been able to trace it back any other way. Also found out once it was hooked up that I had a short to ground that I was able to correct. Very easy to use just watch a couple of Youtube videos. Well worth the price versus calling an electrician in to troubleshoot and repair.

Less expensive version of a toner - does not disappoint!
First off - the description makes note of using this on low voltage. They mention ethernet, thermostat, network, HVAC, etc, etc. I purchased this with the intent on using this on 14 gauge romex and it worked PERFECTLY. (Circuit was off obviously). I needed to chase down some weird line of romex and see where it went so I could remove it form the panel. The toner picked up the wire with ease and I was able to isolate and remove the wire. Pros - I've used the more expensive brand (it's blue in color, every electrician has one) before and it worked well. I can't say this one was any different. And about 1/2 the price. It comes with a case and can even isolate specific pairs in a bundle if you short the correct pairs. Cons - I haven't found any yet. But I will update this if any problems arise. I haven't tried this outside with any buried wires yet. Summary - Great product. Great for tracing low voltage or high voltage capable wires. Good value

Excellent Klein Tool! Poor Generic Batteries!
Anyone purchasing such a tool will likely know the specs prior to ordering as this is something that you would purchase with a particular need in mind. That said, I compared many of the usual suspects when it comes to VDV, telecom, and the like. Some of those brands include Ideal, Cisco, and of course Tempo. I have always been partial to Klein’s hand tools, but the quality of their test equipment surprised me as of late and I’ve been going with more of it when a particular project does arise. I’m long retired, so it’s usually for something around the house, but I detest cheap tools as you definitely get what you pay for. Many years of professional use has fostered that slogan into a very lucid reality. So, Klein has beat out the competition for value hands down. And, I’m not surprised either. You get the features that you would need and then some, and at a price that is a third to half of what you would pay for a comparable unit produced by one of those other major manufacturers. Now, my ONLY issue and the sole reason that this is NOT a five star item, is because ALL of the batteries were faulty. They were all dated for 01-2027, but it’s currently 06-2024 and they don’t have enough juice to power either piece as each one called for 4 AAA batteries. So, I was forced to grab 8 of my trusty Amazon Basics AAA batteries and it was all working great as soon as I fired it up! I’d definitely recommend the product, but please don’t even bother with the included generic alkaline batteries! Even if they did put out enough power, I don’t think I could trust them. The actual Klein branded product on the other hand, now that’s a name I could trust!

BAD BATTERIES!!!
I had all the outlets from one breaker go out...but breaker was fine. Was at the end of my patience and ordered this toner and probe. I watched a view youtube videos on how to calibrate it and within minutes I found my problem. The tool worked perfectly. However, do NOT use the batteries it came with. Upon delivery I put the batteries in, played with it for awhile, to be sure I knew how to use. The next day I get out, ready to trace. The probe turns out, but won't pick up the signal from the toner. I was stumped, it worked 12 hours earlier. I decide to package it up and return, which meant removing the brand news batteries it came with. Opened the battery case and found one battery had leaked all over the inside. I took it out, cleaned it up and put in fresh batteries and worked great. Tool great, batteries very bad!!!

Tracks wires behind walls and floors without opening up the walls or floors
This product worked as advertised! I had to help someone find why they had no power at their outlet. This tool when hooked up to the outlet in question helped me find a hidden outlet (junk hiding it) where the root cause was found. 2.5 hrs later and everything worked as should. This tool is awesome!! Just remember that the power must be off or it will arc / pop. Follow the instructions to the letter and you will be fine

Using this tone generator, I discovered that the break.
I had a series of electrical outlets that suddenly stopped working, there was obviously and connection break but it was inside a wall somewhere. Using this tone generator, I discovered that the break was not in the wall but in the attic. From then on, it was an easy repair.

With practise tracing is brilliant
Worked as described. Recommend watching some very good you tube videos on how to use this product. Although the tone is useful the light is what provided the best tracing ability in the field. I needed to track multiple wires through multi switches and it worked perfectly. I highly recommend this product for diy.

Buena calidad y funcionamiento
Se siente y se ve de buena calidad, funciona tal como lo indica el manual, con el tiempo comprobaré lo de la calidad pero de momento me funcionó perfecto para seguir unos cables tal como lo necesitaba.
