Magnet Fishing is a relatively new hobby that is sweeping across the US, UK and many other parts of the world. Many of the people who start in this hobby use it to diversify from metal detecting and share an interest in history and treasure hunting. The idea is pretty simple really. It’s as simple as throwing a magnet on some rope into a river, canal or lake and hoping for it to attach to some metal. You then pull the magnet back onto dry land and hopefully have treasure on the other end!
