Review on ⚡️ Versatile Voltage Detector: 5 to 1000VAC, 5 In. L - Reliable Testing Tool for Electrical Applications by King Reeves

Not all voltage testers are the same. I bought several different brands online and sent them all back, they seemed a better way to tell if there was electricity in the house. As soon as I placed the other detectors anywhere near the junction box they would set off an alarm rendering them useless as I already knew the junction box was powered. The goal here was to detect electricity in a single circuit. The "Greenlee GT-16 Adjustable" sets the standard for everyone else. Not only does it detect power on a single circuit, it also detects nearby power as it is adjustable, making it easier to see when all power is off.
