The Cable Short Detector look jolly useful. Ex-pecially if you’ve got a short in a cable, I suspect. Otherwise maybe not. Am I blathering? $359.95.
Here’s a way to find cable faults with accuracy. No more guessing where the problem might be. Works on virtually all two or more conductor cables. Just attach the two leads to one end of the cable and take your reading. You’ll know in an instant where your problem is. Accuracy is +/- 2 feet for cables shorter than 10 feet.
