Klein Tools VDV500-705 Wire Tracer Tone Generator and Probe Kit for Ethernet, Internet, Telephone, Speaker, Coax, Video, and Data Cables RJ45, RJ11, RJ12

For the price, this set works well. Comes with batteries already installed and ready to use.

Very effective and easy to use

This wire tracer has saved me so much time troubleshooting bad cables. No more guessing which ethernet or coax line is the problem - just hook it up, follow the tone, and you've got your answer in seconds.The accuracy is spot-on for tracking wires through walls or bundles. Build quality is solid - the materials feel tough and well-made, not cheap plastic that'll break after a few uses.Super easy to use right out of the box. Works with RJ45, RJ11, and coax connections without any fuss. For the price, it's great value considering how much time it saves on cable work.Highly recommend if you work with wires regularly. Beats the old trial-and-error method by a mile.

It seems to do its job well, but some cons stand out for me. It came with weak/drained batteries that failed on me during first day of use. It would have been nice to have an extra switch of some sort on the tone generator wand that prevents it from accidentally turning on while it’s in my backpack (it turns on using the spinning volume dial). As others pointed out, it would be nice if the tone was louder on its max setting, as plugging in headphones/earbuds during real-world use is not always a realistic option when you’re squeezing through messy wiring racks and don’t need yet another cord to snag on something.

Works perfectly. Tough to hate a on a tool that does exactly what you are expecting it to do. It traced each line accordingly and had no issues. I was able to organize a wildly messing server closet servicing a 12,500 sq foot office space. Very appreciative for what i was able to get done with this tool.

Good

I bought this, to trace about 40 cables inside our office, that were installed by a sub-contractor that didn't bother to label anything. When an issue arose, nothing was marked, so it was difficult to trace the LAN cabling back to my network switch.So, I bought this set, and waited a few weeks, to ensure that we had enough time to broadcast to employees, that there would be no network available, this last weekend.Unit worked ok on the first day of use (Saturday, 11/15/25).However, on the second day of use, it would intermittently stop sending tone. I had to turn it off, turn it back on to re-establish a signal tone. After the third time of this happening, it would not turn back on. (I assumed the 'starter' batteries were dead, so I went and bought brand new AAA batteries.) Replaced the batteries, and now it won't turn on at all. I bought an 8 pack of batteries. Tried all 8 batteries in the unit, ensuring each time that polarity was correct. Still won't turn on.Tried to troubleshoot, using the Product Help option. It was no help. Appears it was written for a completely different item? My set, does not have a Power button, and the instructions tell me to 'press and hold the power button'... Usually Klein tools are worth the extra $$$ spent. However, this is not one of those times.

I picked up the Klein Tools VDV500-705 Wire Tracer out of pure frustration—and it ended up saving me a ton of time and guesswork.We recently moved into a house that was prewired for phone and data, which sounds great… until you realize none of the cables are labeled. I had a bundle of mystery wires in the utility panel and no clue which room any of them went to. Trial and error was not cutting it.Enter this tool.Setup was straightforward. I connected the transmitter to a line in the panel, grabbed the probe, and started checking wall jacks around the house. Within minutes, I was able to identify exactly which cable went to which room—no more unplugging, guessing, or yelling across the house for someone to confirm.The tone signal is clear and easy to pick up, even when dealing with a bunch of wires in close proximity. The probe is sensitive enough to trace lines cleanly without being overly confusing or picking up everything at once. Once you get the hang of it, it’s actually pretty satisfying hearing that tone lock in on the right cable.Build quality feels like what you’d expect from Klein—solid and reliable, not a cheap throwaway tool. It’s compact, easy to carry around, and simple enough that you don’t need to be a pro to use it effectively.If you’re dealing with unlabeled wiring, networking projects, or anything similar, this tool pays for itself almost immediately in time saved and headaches avoided.Bottom line: turned a confusing mess of wires into a clearly mapped system in one afternoon. I should’ve bought this a lot sooner.

Poor quality toner can't hear tone if cable more than 1m long

Quality is very good and given before timline delivery because I mentioned need urgent delivery...thanks to Amazon

Good overall product, not great reach of the probe. Approx 5 cm from the cable when searching.

Doet niet wat het beloofd. Utp-kabel kan niet gevonden worden in de muur.

Works as instructed
