Any devices that are used for transmitting data, such as radio receivers, TV antennas, WiFi routers and cell phones will use radio waves. Both kinds of frequencies can be detected with a handheld detector. ... Some RF detectors can detect lower-level EMFs, which can be useful if you work in electrical engineering.

How accurate are RF detectors?

The device has three detection modes RF wireless signal detection, laser scanning, and magnetic field signal detection. You can accurately detect 1.2G to 5.8G wired or wireless cameras, GPS locators, car trackers, wi-fi router, transmitters, magnetic suction positioners, mobile phones, and many other equipments.

What does an RF detector detect?

RF Detector. The RF Detector, like most bug detectors, detect radio frequency signals sent from listening devices such as electronic bugs hidden in objects, or covertly placed in rooms.
