These devices by their nature are finicky due to interference from outside factors. But having said that, this item really works. Originally bought the harbor freight version to try and track down a break in an buried invisible dog fence wire, which did not work and discouraged me from the technology. I tried the Klein version as a last resort based on the recommendation of a friend and it helped find the break quickly. Have used it several times since then for inside home wiring with success. Not perfect, but it does work and can be a huge time saver.

Does this work on tracing 120V circuits or just low voltage?

Looks like it does fo regular wire. It for some reason only markets the low voltage.... at least from the reviews it seems so and the alligator clips

Anyone recommend anything good for just trying to figure out what speaker wire is for which wire, I did not label any of mine. Thanks!

Do you mean which end is which in a pair? Or in a bundle of pairs? If it's the former, one wire usually has printing/text on it and the other doesn't. The other method is how the wires come apart as you split the tear. One is left with a valley and the other has the excess material.

If the wires arent labeled to where you can tell which one is which. You just need a multimeter with continuity tester, it will beep when you match two wires. You can use the process of elimination or Use a spare long wire and tie one end to the wire you want to identity. Almost every multimeter has a test, it has a symbol like sound on the dial.

The Klein Tools VDV500-920 is also on sale for $150. I have both the 820 and 920. Both are good at their respective prices. The 920 does digital so you can easily trace cables that are plugged into switches which is extremely helpful if the network is up and running.

No. You'll fry the unit.

Use a 9v battery. When you touch both wires to the terminals on the battery it will generate a scratchy sound as you tap the wires on the terminals. Pro tip - if you need to identify the polarity, watch the cone of the speaker. When you have + to +, and - to -, the cone will extend outward.

Are the prices accurate? $20 off isn't really that great of a deal, but the added features would be nice.

I used the cheapest one they sold at Home Depot for a couple years. First got it to trace a power cable for a circuit that wasn't making sense. Turned out there was a box with 2 wire runs behind the drywall. Which is against code. Not sure what they were thinking. I forget what the actual issue was. it was messing up the smart switches I was trying to connect that it was feeding into a 4-gang box. I fixed the wiring issue and then adding an outlet there instead to be able to service it in the future.

It also helped me trace out wires when I moved into my most recent house. Trying to find where they terminated down in the basement. Overall really useful. It is very flakey when using to trace power wires. Make sure you disconnect at all ends. Plus the tool wasn't always working, I even opened and RMA on it once because I was so pissed.

The one I have has the built in network cable tester and one of the LEDs burnt out or failed in some way. I lost an hour re-terminating ends last time I used it, eventually I realized the tool was broken.

I'd jump on this deal if it had a network cable tester built into it.

Only 500-920 has the network port so I had to buy that one, even 500-820 is cheaper. Basically my contractor accidentally covered the network port with drywall, so hopefully 500-920 will help us find where it is.
