As an electrician who often works alone, the Fluke ST120+ GFCI Socket Tester with Audible Beeper has become an essential tool in my bag. The audible beeper is a game-changer—especially when I'm troubleshooting or trying to shut off a circuit and the panel is out of sight but within earshot. Being able to hear the tester respond saves me time and steps, and the sound can be turned off when not needed. It’s built with the quality you expect from Fluke, and while it’s a little pricier than some other GFCI testers, the reliability and added features are more than worth the cost. I’ll continue to repurchase this tester and highly recommend it to anyone in the trade.
