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

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.

easy to use
Works great. I bought a house that had both cat5 and cat3 wirings done all over the home. It helped me trace down where everything went in the home and redo and crimp ends that weren't done correctly. Now I have a correctly hard wired and networked home.

Klein makes life easy for technicians.
The Klein Tools VDV500-820 Wire Tracer Tone Generator and Probe Kit is a top-notch tool for anyone working with cables! Here's what I love: - *Easy to use*: The tone generator and probe make it simple to identify and trace cables. - *Versatile*: Works with a wide range of cables, including Ethernet, telephone, speaker, coax, video, and data cables. - *Accurate*: Quickly identifies cable continuity and faults. - *Durable*: Built to withstand tough job sites. Pros - Easy cable tracing and identification - Works with multiple cable types - Accurate and reliable - Durable construction Cons - it is hard to tone when there is interference of radio frequencies. This kit is a must-have for electricians, network technicians, and DIY enthusiasts. The Klein Tools brand is known for quality, and this product delivers. Highly recommended!

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!!!

Use It Correctly
I had moved breakers and wires around in my in house breaker panel and long story short, my kitchen AC is on a single breaker and the outlet had no power anymore. Drove myself nuts for days trying to figure out what I did wrong. Finally purchased this toner and watched Youtube videos and still had no luck, very frustrating . Till today, 4-27-25, heres what I did to trace a 20 amp wire from the outlet to the breaker box. Shut off the main breaker ( whole house ) , then disconnected the Black Hot wire, White Neutral, Bare Ground from the outlet plug itself. Then I attached the RED clip from the toner to the BARE copper end of the Black Hot wire. Then I attached the BLACK clip of the toner to the BARE ground wire coming to the outlet. I then turned the toner to the highest tone setting. Then I turned up the volume on the tracer end and I had one black wire that I had cut for some reason, and that wire I held the tracer against. That was my wire omitting the tone. FINALLY found my issue, so this toner / tracer does WORK. It was probably at least 30ft from the outlet to the breaker box. One Youtube video, the guy explained that you have to trace with the LIGHT, NOT THE TONE. Well thats B.S !!
