Klein Tools VDV500-820 Cable Tracer with Probe Tone Pro Kit for Telephone, Internet, Video, Data and Communications Cables

Items works well, I have never used a toner that was perfect, they can all be a bit staticky if that is a word. This did do what it was supposed to do though. Let me trace some 110v electrical wires in my home. At one time I used these for work for IT cables often. They will let you trace any copper wire but you do need access to the actual copper part of the wire with either the clamps or the connector.

Worked as advertised

Great product. Could use a RJ45 female-to-female coupler in the box to connect the provided RJ11 plug to an Ethernet cable for troubleshooting Ethernet networks.

I was able to easily trace a wired alarm system throughout my house. Well worth the money! I would but this again without hesitation.

Had to tone cat5e wires in a 7500 sq ft home. This tool allowed me to easily locate the correct wire over very large runs and with a large number of wires

I bought this signal generator to help troubleshoot a bad 120-volt circuit in my motorhome. There were no schematics to use and the manufacture was bought be another who said they had none as well. This tool is not to be used on energized circuits. The outlets in the front up behind the tv were dead. I found a piece of Romex behind an outlet by the bedroom tv that wasnt connected. I tried a continuity test with the conductors and the front outlets but there was none. The front Romez disappeared into the wall that was that for tracing. I have a generator for tracing house circuits but the circuit needs to be energized and this is dead. When this one arrived it was packaged nicely and had everything needed to get started immediately. I connected it to the front Romex conductors and was able to trace the signal through the upper front cabinet into the ceiling down the ceiling through a couple of closets rite to the end of the disconnected Romex. The wires were concealed in the ceiling the whole way. The Romex must be damaged in some way but the signal was still able to transmit to the end of it load and clear. After a week of searching and testing, this little tester made short work of an impossible situation. After rerouting a new piece of Romex the front outlet are working.

Accurate to the money

Coming from a electrician of 16 years this is a time saver doing remodel work very easy to use ive used it on several jobs enough to have a good opinion on how good it is and it is very accurate for example you can connect the meter to a home run and use the probe in the panel to find it by runnning it close to breakers would definitely recommend to another electrician as its a must have

GOOD

I originally bought this to trace a short in a wiring harness. That project still hasnt gotten off the ground (the short is intermittent and has decided to go away for a while) so this tracer has been in my toolbox for months.
