I used to be into metal detecting aka TH’ing (treasure hunting) a bazillion years ago. I still have two detectors around here somewhere. I couldn’t help but do a double take when I saw these metal detecting sandals from Hammacher Schlemmer that come in sizes for men and women. The right sandal has a built in coil and a control box that straps to your calf. When you walk over something metal, an LED will flash and the box will buzz or vibrate. For $60 bucks, you can slap these polyurethane flip flops on your feets and go find yourself some gold doubloons. Yo ho ho!
