Can't answer that question HH. I think having a powerful 4 coil trap in the ground that can break through the frozen dirt is more important. If you are bedding in peat, I can see the nail thing working. HOWEVER, I know as a farmer, I'd be PISSED If I had a flat on the tractor out in the field because of a 12 penny nail come spring!!! I can see those nails getting flipped up out of the set and being lost. The way my luck goes, I'd do it to myself!!! :rolleyes:
