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

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.

Works great for my needs. Gives a good strong signal when it picks up the tone and I can check my connections to make sure I wired and crimped the cat cable correctly.

The tracer ; It is a Great tool ,amazing! Really cheap and helpful It saved my life finding and giving solution to my trouble! Shooting!

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.

These tools work great for tracing electric cables or Internet cables.

Excellent. Used it in the office.

This wire tracer kit is okay for basic jobs, but it falls short if you’re doing frequent or more demanding work. The tone generator works, but the signal can be weak over longer distances or in noisy environments, making tracing a bit frustrating at times. The probe is durable, and the built-in light is handy, but the audio volume even at max can be hard to hear in a busy job site. The included accessories (like the alligator clips and RJ45 cable) are nice touches, and the wire mapping feature is a bonus, but overall it feels more like an entry-level tool. Good for occasional home use or small projects, but I’d recommend looking at higher-end kits if you need something more reliable and consistent for professional work.

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.

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.

Tester not working properly

Works as instructed

Worked like a charm and came with batteries unlike the red one which needs 9v
