I am reading a lot of you fellas detecting corn fields and hay fields lately. I was wondering if you do some research to see if the field has had a house on it at one time or not, or just take your chances and see whats in the ground. I have tons of agricultural fields around me, but I have never hit one. I think to myself, its just a cornfield, and the chances of me finding the spot where the farmer pulled out his hanky to blow his nose and lost a dime is like a needle in a haystack. I would really like peoples input on the theories of what people do and think about agricultural fields... thanks in advance
