I was able to go out for a while tonight. I switched back to the 8.5x11 and put a little terminal grease on the pins for better current flow then plugged her in as tight as I could. Pulled the coil cover off and cleaned everything up real good and put it back on. Factory reset the machine. Ran an auto gb, then adjusted -10. Set pro custom, iron disc @ 35, nothing notched, sens 1 below max. Finds were 1 quarter 4", 1 nickel 4", 4 dimes-shallowest 2" deepest 6", 6 pennies between 2" and 8", and one small childrens "tot lot" ring at 5". I even got a solid 54 (thought it could be a nickel) turned out to be a pull tab, but it rang in at 8" on the detector, actually dug 10 to get it. I am gonna go out on a limb and say that I may have solved the problem. Not sure if it was dirt in the cover, bad connection, or just needed a factory reset that bad though. Anyway I thank all of you for the advice and assistance that you have given.
Metallic sand & dust inbetween the coil and cover cause all kinds of mayhem, it gets worse when you try to ground balance with it in there.
Somebody on another thread said they seal thier coil cover to the coil with a bead of silicone, sounds like a great idea to me!
