Hi all. I'm going up to the my uncle's farm in wisconsin in a few weeks. I will be bring a Whites Prizm 2 with me. The soil up these is mostly clay and limestone and sandstone. Does anyone have any suggestions for working in this these types of soil with the Prizm 2? I will be hunting in "all-metal" mode, since I like to dig everything anyways. I was wondering what I should have the "sensitivity" levels set at? I run mine on no discrimination at all. I will be working in large open farm fields mostly. Thank's all for the help. Sincerely, Randy
