I went to a tot lot today and shifted it into All Metal and full sensitivity. At first I was not thinking and tried to use Disc 1 and almost walked away. Then the light came on in my head and I started to hit tiny targets. First was a fake diamond pin then some iron trash--tiny pieces of wire and necklace chain pieces and hooks, and bobby pins. I was digging everything after checking it with Iron Audio and even if it grunted I dug anyway just to see. I got very comfortable with it in no time. Some iffy targets give a little grunt but others there is no question about it being iron. Then I found a child's ring. It looks silver and says "India" on the inside. Now I might have thought otherwise, but it is the thinnest ring I have ever seen. I mean almost like aluminum foil. That's why I think it is silver. Later on I went back to the lawn area in the park and found a 1946 Roosevelt dime. It was about 8 or 9 inches deep. Not much but it still felt good to see silver. I think there are some other out of discrimination range targets near there but I didn't have my digger and the roots were more than I could deal with, so I'll come back and check it again.
