Keep in mind that my 7200 was out in the snow, rain, mud and frozen in the ice for 4 months
It was completly covered in mud. It works perfectly lie the day i lost it. They are alot tougher then you think. just let it dry for a few days, after a few days blow it out with either an air can or air compresser on low setting.
