Electrician’s magic wand

I noticed several professional electricians using this thing: The Klein Non-Contact Voltage Tester is a small magic wand that beeps when it detects a live current in a wire, or a switch or a cable or anything electronic. The cool thing is that you don’t need to bare the wire or contact, you just wave this near the wire. That is both much safer and way quicker. It can detect voltages between 12 and 1,000 which will be enough for most uses. For me it has replaced several devices in my toolbox I used to use to detect a live current. — KK
