The Elegiant Wire Tracker looks unassuming, but it helped me solve a frustrating problem: identifying the Ethernet cables buried behind the walls of my house. The inexpensive kit consists of a little plastic probe about the size of a Polish sausage and an emitter about the size of an iPhone (only it’s an inch or so thick).
It’s made of blue plastic, so it doesn’t pack that heavyweight “pro” feel, but it seems fairly durable. And if you need to figure out which Ethernet cable goes where, it gets the job done.
