Still having problems

[Rebel1]

I took the 2200 out again today to the local grade school and checked the playground. I found 5 dimes the oldest a 1940, 1 nickle, and 7 pennies along with an assortment of nails, screws, wire, and zipper pulls. But every once in a while i still get a good tone or 2 but when i go back over it either no tone or the tone changes. Is this normal. I tried discriminating iron but still had the problem. I am keeping the coil level and at or just off the ground. I have a coil cover on it. So, any ideas? I tried air testing it when i got home and it seems to be working although the tone does change on some coins and the readout will say dime-quarter-dime on the same coins. Normal? Any help appreciated. Thanks.

There could be several things going on. Foil always reads a little goofy, it could be playground foil messing with you. The target could be too deep or even a coin standing on edge. Or your disc. can be hiding it on most passes and allowing it on a few. You could also have 2 target in close proximity, lets say brass(steel) knuckles and a dime and your disc. is hiding the steel and the steel is masking the dime. Hopefully whis helps. If all else fail turn you disc off and your sens. up(or down) a hair and go back over the same spot. After a while you will get the hang of it.

i had similar issues with the 3300, and f-4, both good machines but annoying

Thanks for the replies. I think it is most likely just going to take me a while to get used to this thing and to learn its quirks. But it is fun getting out doing it, although frustrating at times as well.

Charles Garrett once said expect many hours in the field before you get comfortable with your unit and certainly was a truism. If you can find a experienced detectorist to help you along your learning period will be much shorter.
