I went out for about an hour and a half in this 94 degree heat with the 2500.I hunted some playground equipment.Not much there.I had a problem with the signals from coins.Pennies came in as a low tone,not a belltone.Some of the dimes hit 1 or 2 notches below pennies and didn't belltone.One dime hit as a nickel.Only quarters would belltone.The ground is powder dry.Nickels hit a little lower on the scale.I was in factory preset coins.Could it be the school ground,mineralized?I made sure I had the targets centered well when imaging and pinpointing.Any ideas on what was going on?Thanks Bill

My 250 was a bit "off" today as well.
I think, as you said, the powder dry soil may have something to do with it.
Half inch below the grass roots my soil was like digging in dust. Really had to work to pinpoint my targets accurately. They sounded funny too.

I have never had that trouble. Here are a few tidbits that may help. The deeper the target the less accurate the ID. Generally this occurs at around 6 inches. That is not to say that it won't be right but it is correct less often deeper than that. I dug a copper Lincoln cent today that was about 7-8 inches down and kept IDing as quarter at 5 inches. As for your dime that hit as a nickel I would say there was something else in the hole with it. One of my favorite finds is big coin spills. You would be surprised how many ring up as zinc cents. For example. A quarter and a nickle back to back ring up as a zinc cent. Today I got 5 dimes, a nickle, and 3 pennies that rang up as zinc cent, size C. Check the coil connection. Sometimes mine gets loose and causes falsing. Check that a button is not stuck in the depressed position. Check you sensitivity. Adjust it so there is very little to no falsing whichever you prefer. UW always says 6.5. I generally run a bit higher than that depending on the site.
Zinc cents, IHs and early wheats do not belltone. Most copper cents do but there are exceptions. All dimes do although I had a badly burned mercury dime ring up without a belltone. The best way to tell a dime from a cent is dimes frequently image as size A. Wait until you get a badly mangled coin. They can hit anyplace.
The dryness of the ground isn't helping your situation. Air test your machine with various targets and get an idea around where they hit. Air testing results are different from actual hunting but can be used as a guide.
