The Perfect Vision Pocket Cable Tester is a great little tool for testing cable systems in just a few passes. I bought this tester to test 10 new runs of RG-6 after my house flooded and to make sure our drywall technician didn't go through any of them. Pros: - Small (really small) - Signal receiver is very noisy. - You can hear it from the other end of the big house (it saves a lot of walking to see if the signal was received). receiver, this tester is not very effective when you are working alone or need to test many cable runs.
