All the features work well but this week end it really saved the day. I had an unmarked cable going from the roof to the server room I was trying to locate. I normally use a Fox & Hound tone generator and amplifier but the problem with that is it picks up noise and interference in nearby cables and completely drowned out any signal. And the tone loses volume down the cable.
Although I HAD complete faith in my Fox & Hound I thought I'd try this new tester. It was amazing. I found the cable in 5 minutes. There was no noise or interference. And even at the very end of the cable, plugged into a network switch, the signal was loud and clear. What we could not do in half a day of testing we were able to do immediately with this tester.
