Klein Tools VDV500-820 Wire Tracer Tone Generator and Probe Kit Continuity Tester for Ethernet, Telephone, Speaker, Coax, Video, and Data Cables, RJ45, RJ11, RJ12

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!!!

Make sure you watch a video that tells you how to make the pairing initial adjustments when the devices are turned on and adjust the sensitivity; makes a huge difference for first time users. I was able to track down a hidden GFCI outlet that was behind some cabinets in a garage and protected all the outside lights. Also, some of the batteries that came with my unit were almost dead, took me a little bit to figure out why the unit turned on but didn't seem to work properly. Great product for tracking dead circuits; I highly recommend it.

Worked great for tracing ethernet wires for a POE security system. The wires disappeared and reappeared throughout the house and this made quick work of know where each wire terminated, cut, etc.It probably does so much more, but did the job I needed it to. Well built and will be using it more often.

I didn't know this tool existed. I saw a video on Youtube when trying to find out why one of my plugs wasn't getting power. I was so frustrated i was about to start carving holes in my walls to figure the problem. This tool lead me right to the problem. A plug in a diffrent room was wired poorly and i was able to fix it in minutes! What a life saver! Works well:It gives off a strong signle even when your far away from the plug so it's very easy to track down the problem

I read several reviews of this product where customers noted the tone generator and probe did not stay on for more than a second or two. I also experienced this using the AAA batteries that Klein shipped with the products. I changed the batteries for quality AAA batteries (Duracell) and the devices work great. The batteries were the problem. They are junk. Klein, please ship this product and others with quality batteries next time.

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 !!

I love it! After 20 years in the industry, I’ve only ever used the same $30 toner. Listen, it got me this far and it’s fine….this is just better. Speaker is louder, easier to use, and just plain old higher quality.

Si, de herramienta muy importante y buena para electricista
