Review on Electromagnetic radiation detector BENETECH GM3120 by Mateusz Jankowski ᠌

Suitable for household measurements: it is convenient to localize the source of increased EMF and determine a safe distance. They can also look for wiring in the walls. It should be borne in mind that the device does not show radiation from cell phones, towers and routers (it is not designed for this), only from household appliances. Pros below: Instantly and accurately shows the electromagnetic fields of household appliances. Very simple and reliable. Its cons: If held in hand, it shows all the EMF received by the body, this nuance is solved by using a selfie stick.
