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

This is an AWESOME tool... I wish I had bought this years ago. Saves a lot of time... the YouTube videos are accurate and the product is very easy to use.

I was in the worlds worst hunt trying to figure out where some network rack ethernet cabling routed through a building. Tried the two wire RJ45 plug that is on the unit and could barely hear a peep. Decided to make an adapter and twisted together all 8 wires to a ring terminal and fashioned the key to success! It worked so well I was able to pinpoint approximately 200ft away where it ran through both metal sided walls and sheetrock walls. Life saver! I just wish they had included a full 8 wire RJ45.

A good product

Takes a little getting used to but not bad. Worked great and helped me.

My husband uses these for his electrical jobs and they work very well.

I like my tester so far I have used it twice, I hope it will last me for a long time

Very well made. Toned cat5 wires four floors away without issue - strong signal & adjustable signal tone a great benefit. Very sensitive -- in addition to finding appropriate wire, it picked up data traffic in adjacent wires and sounded a different kind of tone for that.

I used this to find a short in my house and WOW did this thing work ! Awesome product and great quality

This tool has saved me time and mega problems. Very good for tracing wires not landed in electrical panels. Easy to use to locate and trace wires within the walls and ceiling. A life savor for sure and you cant beat the price.

Its a good quality product, feels solid. My only complaint is this would be so much better if it could work with an active network instead of only inactive wiring
