Thanks for all the help. Was a very interesting day. I think the fact that I was in an area rich in Iron ore, probably one of the richest Iron ore areas on earth, threw the thing a little. I would get a target ranging from 34 to 40 at a maximum depth. Would start digging - scan again the reading would disappear. The other reading I would get sometimes was 2 to 3 (earings symbol) again at a maximum depth. Scan the area again and it would disappear. Scan it again and would get a weaker hit in the same place. The area was hard to explore due to thick mud, inclines and heat. Also had the distinct feeling I was being overlooked by a jaguar at one point.
BTW, what is the symbol next to the earrings at about 5. Is that a wrapper? Could not find a description of the symbols anywhere. Is the symbol at 25 a bottle cap?
