Took my Infinium LS to a Elem. school to see what the Pro and Ace might have missed. Soon as I started I knew something was wrong. The Finney was sounding off on every swing. Nothing I did would quite it down. So moved over to a little used playing field & managed 5 Quarters and two cents. Back to the truck, grabbed the Ace 250 , hunted without a problem. Grounds keeper came over for a chat. Said where I was hunting was where they knocked down the old school 20 years ago. Lots of iron and such buried there.
Case solved.

Ace managed to sniff out 13 coins (all clad) from a small area that was just too hot for a PI.

Don't dismiss the area as being too hot for a PI when in fact it was too hot for the Finney, a certain PI. It's too bad the finney doesn't have adjustable gain and ground balance. One of the reasons I prefer the TDI over it. Garrett wanted to keep it simple but in doing so they sacrificed some neat tricks PIs can do...I'd be interested in giving that field a go if I didn't live so far away. Deep iron masking shallower targets is always something in the back of my mind. When people switch to a smaller coil and suddenly find things that "weren't there before," they usually attribute the new success to target separation. I think this is part of the story, the other part is the smaller coil doesn't pick up on deep junk. Good on you for trying another detector when the first one didn't work :thumbup:

P.S. Near my house there is what I call the "field of doom." It has so much iron, deep and shallow, that I only had the patience to hunt it when I was a noob and finding a bottle cap made me happy. I have no idea how, but I pulled a silver quarter out of it. Also found a cap gun and some lead toy soldier. But let me tell you, I don't go near this field anymore. PI, VLF, doesn't matter...the iron will defeat you.
