How to Make METAL DETECTOR - I Found something strange in my backyard

How to make a powerful metal detector at home. I made this simple and at the same time amazing idea in 4 days. And the result impressed me. The metal detector really works, I found metal parts about which I did not even suspect in the backyard of my house. Guys, at the end of the video there is an assembly scheme, I can also upload additional pictures to the community. Wrap 25 turns of copper wire on a spool. Thanks for watching my #DIY video.
