I like it a lot better than my vdv500-123 the vdv500-223 can tone active lines and has a more distinctive tone to pinpoint the line better but if you wanted analog it will tone analog or digital it’s a better value because it does so much more I use my Klein vdv501-770 scout pro max for the tone generator Read more

Worth every penny! I solved my problem very quickly. Needs a little bit of getting used to and a short set-up. Read more

Signal strangt no good Read more

Have used the platinum grade toners and this does same job. Comes with a bag you cannot see so no need to buy extra. Don't forget rj45 female to female adapter for plugging to cables (rather than outlets). Read more

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 !! Read more

Good quality item, arrived on time Read more

Great tool , must have if you working in this environment, quality plastic, easy to use , not cheap but more quality then other hope it will work all the time no issue . Recommend Read more

I started out trying to trace ethernet cables with the VDV500-123 and the Klein Lan Scout Jr 2. This worked ok as long as you could touch the cable with the tip of the probe but didn't work through walls or even wall plates. I tested the output of the Lan Scout and it was only about 1.18V into a 10kohm resistor, or about -8.5dBm of power. The Klein VDV500-705 says it puts out +8.5dBm for toning, so I hooked an audio signal generator to my ethernet cable running at 1kHz and 7 volts, or about 7dBm. This let me detect a cable with the VDV500-123 out to around 6-12". It would go through walls with no problem. This let me trace my wires all over my house. The only problem I ran into was that wires that were bundled together for long distances would couple the tone signal from one into other ones. Once I found all of the points the wires ended at, I could still tell the difference between them though. Read more

Llego en perfecto estado, y funciona a la perfección, lo recomiendo 👌🏻 Read more

Purchase this one alongside with the Scout Pro 3. They work well with each other. Read more

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 Read more
