My son opened my eyes to this hobby. Brought a couple of decent spinners the other day. He says he pulled him out of the river. On a search magnet. This is, they say, a fashionable hobby in the country among treasure lovers. You can also find weapons of the times of the Civil War, Patriotic War in the reservoirs. Then the front-line soldiers brought home a lot of battle trophies, and then they had to get rid of them. Interested and want to know in more detail what is magnet fishing read a detailed review.
