I use iron mask to cover about 1/4 of the screen. Then I hunt in digital for grass lawns. Have to pass up some iffys but want to be able to come back Got out for an hour today. Open fields have thawed. Only dug a nickel and a wheat, but for field hunting it lets me know I am in a hunting spot. I was set up for the woods with a 5" coil but we still have a frost line there. Today started with a heavy frost, about 20 F but then warmed up and was beautiful. I think our season has started. We may get more snow but I don't think the ground will freeze again.
