Review on JOAUIAX 5HZ 3500MHz Electromagnetic Sound Light Inspections by David Herman

Office. EMF testing and ghost hunting. This is a fairly lightweight and relatively easy to use Electromagnetic Frequency Detector designed to detect the magnetic fields of voters around you. It's not the most precise and accurate instrument, but I think it's a very good fit for a device in this price range. It tests 3 different types of measurements, it can store the peak value and some other functions. Read the description to make sure this is the right gadget for you. I would also suggest doing a little research online about EMFs so you know what you are looking for and what the results mean. It's also a flashlight. You can also use it to detect electromagnetic fields from unknown sources. For that, you can look at Ghostbusters as a research tool. lol
