Hi guys. The spherical band is actually a copper band that a lot of old timers wear as they think the copper is good for arthritis. I haven?t found much of value as I don?t do this very often. I can?t get out into the bush at the moment as the ground is very wet. I just did some beach detecting for a bit of fun with my daughter and the grandkids over Easter. I went out again this morning and had some more fun. I found enough to buy a cup of coffee. (It?s just the thrill of the hunt) Next time I?m out, I?ll take some shots of the beach that I?m detecting.
