I was wondering if anyone can help me with a pretty basic problem. I'm still digging far too much junk iron, nails, even foil. I've tried Basic 1, Deus Fast, and Basic 2. I tweaked it a bit at times by raising reactivity to 3 or 4. Iron volume from 0 to 4. I ground balance manually. I pretty much dig any high numbers and still dig a lot of old nails and old rusty iron in areas of cellar holes and old house foundations. I even dug a whole bunch of old cans and bottles with caps. I'm digging about the same stuff as my girlfriend who's new to this and using a Bounty Hunter Quick Draw 2. Kind of embarrassing. Can someone please give me any configurations you've used that rule out iron and other junk as best as you can. Also, how accurate is the Ferris vs. non-Ferris horse shoe icon on the screen. Looking forward to any help. Thanks.
