I went detecting near an old castle ruin the other day.. When I got in the middle of the field to set up I found that my WM10 and headphones were not in the bag, I noticed that the zipper was open. I was really upset so I went back to my car retracing the route I came. I had gone through some brambles but all I could see was a soda can. I rang home to see if it was left on my bed or on the pathway but it wasnt. So I went back to the field again to look. As I went through the brambles again I saw the can again, but as I looked I realised it wasnt a can but the WM10, the Minelab symbol made it look like a can lol. was I relieved. It was night time too...Phew...
