Detektory metalu, drewna i prądu - działanie i testy

Have you ever drilled a wire, wanted to hang a TV, but don't know where the profile is in the partition wall? Metal and electricity detectors can help. In this video, you'll see how a detector works and I'll test several such devices. I don't provide renovation services and don't offer advice. In my videos, I only share my renovation experiences and don't constitute professional training. My methods may not always work in all conditions. ✷✷✷✷✷ VISIT ME ON ✷✷✷✷✷ FACEBOOK -   / mariobudowlaniec   INSTAGRAM -   / mariobudowlaniec   WEBSITE, ✉ - http://mariobudowlaniec.pl
