Probably going to seem a weird question but does anyone know where I could get a 'Moon Compass' ? I was briefly shown one by an instructor who was taking us through the basics of survival and navigation. Apparently it worked by taking a bearing from the moon etc etc and consisted of a just a couple of laminated sheets of cardboard which he'd photocopied out of some old magazine. I've tried searching on the web and had no luck, ..... so I thought with the combined knowledge ARRSE I might be in with a chance !!!
