Review on 📡 GQ EMF-390 EMF Meter & Detector: Tri-Field Electromagnetic Radiation Detector for 5G Cell Tower, Wifi, Data Logging, Spectrum Analysis, Radio Frequency Detection - Ideal for Ghost Hunting & Beyond by Pavel Craig

Ready to use. Bought to take readings from an outside power line maybe 200 feet from home. Readings were mostly zero EMF (with "normal" readings) even from the yard, but I was surprised to see this thing beeping (with "high" readings) on 2 things on the bedside tables. One was a wireless charging alarm clock and the other was an LED magnifying lamp. Deleted them right away. You can tell people all about RF/EM, but when they see it with real numbers and a beep, it becomes so much more compelling! Easy to work with - no instructions read - easy to read and handy size. I love that it beeps when it's "high" and that it hits 10 gigahertz, which most others in this price range don't have. The battery is excellent, there is an indicator when it is low.
