If I had a gold coin for every time I was out detecting and someone asked me “Do those things really work”? I’d have retired long ago.
I’m always polite and enthusiastic with my responses to questions or comments, after all, it is Metal Detecting. What detectorist doesn’t like to talk about that? But, after years of being asked the same question over and over again, forgive my imperfection, but just once, I wish I had the nerve to respond with “No, they don’t work at all. I just love scanning the ground all day in my silly little world of metal detecting make believe”.
