Yep... well I went hunting yesterday in a blizzard here in northeast Ohio, I live in the snowbelt area.... and those Spitfires worked agin.. You know I was thinking in my tree stand about I wonder if they might freeze in place and cause a problem!! It was snowing and blowing sometimes ice balls. I was concerned about the blades sticking... Well after last night, I will not even worry about that any more. I harvested a nice 8 point at 25 yards and they worked as good as if it was 45 deg. He went about 60 yards and ran out of hot air at that point. After field dressing, I checked the other broadheads in my quiver to see if they were frozen. No problems there eather. However my Dry Plus was snow,ice covered so much it looked like snow camo......
