Don't feel to bad. Heading home after a couple of days detecting in the Triangle (with my ordinary shoes on). Decided to stop and try a little spot I'd had my eye on for a while. Very long grass and looked really "snakey" so I put my gumboots on just to be safe. I had about 10 minutes of extreme frustration with the machine howling and me fiddling with the controls for no effect, until the penny dropped. Steel caps in the gumboots. I looked around to see who was watching, cause there usually is when I do something really stupid. I thought I heard some laughter, but it must have been my imagination. Anyway, back to the car and continued home. To disgusted with myself to do any detecting.
