The Ebtech Swizz Army Cable Tester will earn its keep over and over. It's multifuntional and will display the precise wiring of any cable or adapter - even allows testing of installed cables inside walls. Another cool feature is its patented intermittent detection, which lets you wiggle cables to reveal intermittent problems, the kind that usually go undetected. The Swizz Army Cable Tester also functions as a tone generator, phantom-power detect, and grounded XLR shield detect.
