alot of trash forsure, your yard definitely is the worst of the worst for trash. Did you try the Advance smart program where you can X out most of those items, thats why you can't get any depth, to many trash targets blocking the explorer from getting pass them. A small coil would help alot but since you don't have one yet you gotta get bye that trash. By X-ing out the nails and pull tabs and crown caps and bottle caps this should help. I would put a check next to coins and non-ferrous items in the menu and see if you can't get passed all the trash. I'm not sure but in a trashy area like your yard I don't think iron mask would work that good untill you remove some of the trash, maybe someone else reading this has some input. Also Geo, you can teach the explorer to except just targets that you want to find like coins, this might also be the way to go in your yard to get pass some of that trash and there's the last option. And that would be to dig the trash out but man thats alot of trash. Keep us posted Geo on how you come on it, it's a tough site forsure, hh
