As a teach teacher, the students are always damaging cables (by accident) this tools let them trouble shoot audio and video problems in a snap.. Step one in trouble shooting is to check the cable and this tool does it very quick and easy.

Great for trouble shooting

Finally a cable tester that does it all, including B&C. With a bag full of other testers now of marginal use, this tester with the rotary switch will replace them all. Whirlwind knows what they are doing, and did the MCT7 exactly right!

helps in process of elimination. Sometimes you have a bad cable and need to confirm fast

Whirlwind to the Rescue

This is a must have product. It's small, easy to use, and provides quick concise answers to cable problems. I use this to check out my cables before packing up to do an audio or video project, plus I take it with me. I can jiggle the connections as I test to see whether the male or the female connector is bad and see exactly which pin is at fault. Recently on a large production, we had several hundred yards of SDI and XLR cables going from a switcher to multiple cameras for a live event. During the setup we tested all the cables and replaced a handful of cables that had issues. Had we not had this tester, we would have spent a lot of time switching out cables, cameras and wondering if the switcher had issues. The only issue I had with the tester was the battery compartment. The holder for the 9V battery was loose when I got it. It was easily fixed with a few drops of hot glue.

No. The unit is designed to test cables by attaching both ends to the tester.
