Dad and I used to coin shoot around old mine camps and homesteads in the winter in WVa because the brush and bugs wern't bad in the winter. We would go out when the snow was gone,but it was still cold and our detector was a red RAY-scope and had trouble working in the cold.Dad jot a jonnie hard warmer and rigged a pouch on the bottom of the detector with a pad in between them and that took care of the problem.Dinn't do much for the frozen ground though,so we shoveled the finds in a bucket and went through them at home in the basement after the clumps thawed out.
