Just talk to Tim he went hunting already and came back.The one site he wanted to try was to muddy,so he went to another park,and this park was sort of a land fill he uses a ace 250 I have been there with my 250 and all three coils and it drove me nuts,signals every half foot cans and junk but i know there is good items there.They found some Indian artifact there a while back.What amazes me is the 250 works different for everyone using different styles he put it in coin mode and sensitivity down to 3 and was pulling stuff 3 or 4 inches he picked out coins and some baseball coins and not to much junk.I hunt a lot in all metal looking for the one find and dig some deep stuff because in all metal you here everything in the other mode work but sometimes i think the iron over rides the coin and you sweep past it. but in all metal i here the ones that are hiding time and time again but you have to go slow and after you do it and grab a few coins you begun to know what the coin sound like in the iron.Its is warm here today even though there is still snow and ice. I will try to go hunting today.Happy holidays and good hunting. well Tim i have to find something better today .
