TEMPO 802K Digital LAN Network Toner and Probe Kit, Wire Tracer to Troubleshoot LAN and VDV Wiring, Professional Network & Cable Tracers with Wire Toner

I have been using a Fluke Pro 3000 for years but it really has some flaws: no ethernet jack, turns-on accidentally, and it's not sensitive enough to work through walls. The Greenlee 802K fixes these problems: it's 'filter' mode removes the 60 cycle hum that normally drowns-out the test signal so the sensitivity is much higher. I can hear the signal from 5 feet from the wire and follow a wire through a wall. It has an ethernet jack so I can plug wires into it and both units have power buttons that prevent them from being turned-on while they're in your toolbox (this used to happen to me all the time with the Fluke). My only complaint is the long alligator clip wires: they should be jacks so that they can be removed when not in use.In all this is a great tool and worth the $200.

Great toner, but instructions for use are sadly lacking

This might be the best tone generator and toner wand you can buy. Sure, there might be fancier ones, but the quality of these are top notch. Once you use a filtered wand, nothing else will suffice. You really can't go wrong with Greenlee.Highly recommend!

Bag in picture isn't the one that was sent. Worse, the filter probe doesn't fit in the bag that was sent.

This is a great tool for tracing cables and identifying Lan lines.

bought many of these. They're excellent in the field.

Is pretty gd been helping mealot
