Wire Tester RJ45 RJ11 Cable Tracker Line Finder Multifunction Wire Tracker Ethernet LAN Network Cat5 Cat6 with Earphone for Cable Collation, Network Maintenance Collation, Telephone Line Test

If you're doing any type of data or voice wiring just get this kit and save yourself some time and energy if you have a problem. I do a lot of Ethernet wiring and need a kit to track down wire runs and problems. This inexpensive kit has saved me hours of time and climbing through attics. Use it to positively identify wire runs and connectivity of the pairs. Very functional and economical. Battery life is excellent. Couldn't be without this doing my job.

This tracer/tester definitely seems to do the job for me as a hobbyist.I was originally concerned because it was fairly inexpensive, so I didn't know what to expect from it. But I needed something to test some homemade cables and maybe to trace wires in the future. The instructions were brief, but I was able to figure it out without issue. I did test the tracer and it works both with headphones or the built-in speaker, both with a sensitivity/volume adjust. I can't say that it's the most precise kit, but it definitely seems to do what i need it to as a home networker/ hobbyist / small business setup. Good value. doesn't come with a case, so may be worth looking into, but it's well-packed in the box, which I've been using as a case and I'm pretty happy with it.

Good buy for $20. The toner and probe are good. They're not as powerful as my Fox+Hound but way better than my $25 Extech. I was able to tone out a 100ft cat5e line on the patch pannel pretty easily. The tone generator is very powerful and blasts cross talk into 6+ lines but it not too hard to narrow it down to the correct wire on a patch pannel. In a bundle tough, forget about it. Too much crosstalk. Another negative is the tone generator does go through 9v batteries fast. The wire testing works great. You do have to read the poorly translated manual to know how to test for line continuity, polarity and tip+ring. Also the alligator clips are a joke. I also love the on/off switch on the wand so i can tone without holding down a button. Be aware this isn't a professional tool. If you're going to be toning out lines routinely and toning out lines in bundles spend the $$$ and get a Triplett Fox+hound, or Tempo/greenlee. Those probes are way stronger more accurate, much less cross talk, have more features for tracing, and don't eat batteries. But for occasional use or something to keep in your IT dept as a backup its good.Update: so after using the probe with different tone generators and testing them all with a multimeter the secret sauce to this kits performance is the tone generator. The probe is as weak as the other cheap sub $30 probes but the tone generator puts a 7v signal out on all 4 pairs while the tempos, flukes, (and other cheapies for that matter) put a 3-4v signal out on 1 pair. In addition to putting tone out on 8 wires it doesnt put it out on pairs that are connected on the switch end so theres no continuity if its plugged into a switch. This makes it LOUD. The upside of this is you can get a loud tone from a dirt cheap probe because you're basically blasting the whole cable out with tone. The downside of this is LOTS of crosstalk and a short battery life.

A great cable toner

So, it's inexpensive, and it makes tones on wires and lights up if a wire has continuity. Exactly what you were after. Down-side, you have to use the included earbuds to hear the tone. Which, if you're in a wiring closet waving this thing around at the end of your arm you've just pulled them out of your ears and won't hear the tone. Which is annoying. Anybody using a wire toner to find a circuit is not, repeat not, doing so during a funeral, church services, or at the ballet. The earbuds are thus necessary but a great hassle to keep in while toning. The signal strength is a bit weak, in spite of using 9vdc batteries which should give it a little more juice to work with. Continuity checks on ethernet wiring? Perfect tool! I've been a network engineer for 30 years now, I use Fluke products at work because I'm not paying for them. At home, on my dime, this does the job and if I break it I'm out the cost of a Happy Meal. Which, if you use it to tone a 110vac outlet to a de-energized breaker box and then happen to flip the breaker before remembering the tone generator is still in the outlet? Yeah, you're out a Happy Meal. Buy two of these before working on something that isn't low-voltage. I just wish they would have let that built-in speaker in the wand, you know, speak. Like it wants to do. Like it was made to do. Like it was born to do. Other recommendation: get four 9vdc rechargeable batteries because when you slip these into a tool pouch (which is not included and, really? How much can a nylon pouch actually cost?) the sliding switches will invariably slide and run the batteries down, and you will only find this out when you pull the pouch from your tool bag in Reva, SD in a -40F evening trying to figure out why an ethernet jack isn't feeding the WAP in the only motel in town, only to discover the nearest 9vdc battery is 40 miles away. For this kind of money, carry a spare and that includes the batteries too. To Sum, it's inexpensive, works, and is mildly inconvenient. I'd spend a few more bucks on one that doesn't require ear-buds or headphones.

Did exactly what I needed to do. Cheap little build, but works. If you're just needing it for quick ring out of your system and not a professional, it does the job, came in a day and saved me a ton of time ringing out the system to jump a few Cat6 up in the attic. Didn't need headset - it's plenty loud and obvious even when a dual connected cable. Clear as day which one is connected to the sending unit. Good luck with the project!
