Ebtech Swizz Army Cable Tester
The Ebtech Swizz Army Cable Tester is the professional's choice in multifunction cable testers. It displays the exact 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 and discover any 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.
