Hi all. I will be going up to my uncle's farm in Wisconsin in about 2 weeks, and I will be bringing a Whites Prizm 2 with me. The soil up there consists of clay, limestone, and sandstone. I was wondering if anyone had any suggestions on how I should set the "sensitivity" levels on the Prizm 2 to get the maximum depth for the Prizm 2 in the soil conditions I mentioned? I will also be hunting in "all metal" mode, since I like to dig everything. Plus, I don't discriminate anything on my detector. Thank's for anyt suggestions. Sincerely, Randy
