A few minutes ago it was pubished by aquachigger, another amazing video “Magnet Fishing For Fun And Profit: Types of Magnets”.
As informed in the youtube page by aquachigger: “Here is a video where I describe several types of magnets that are good for retrieving treasure. I show the kind you can toss in the river on a rope and also the type you can affix to a pick handle for iron retrieval. At the end of the video I show where you can buy them and the exact model numbers of the magnets shown.”
