Was wondering if any of yous cover your hand grip with anything. One muddy days I will wrap a plastic around the hand grip and I also wrap a bag around the upper part of the shaft the area that I grab when I waive the detector like a pinpointer. It isn't pretty but when I get home I just take off the bags and the grip and rod is nice and clean. I have bought a couple detectors over the years that had some kind of wrap over the hand grip foam, I never took it off to check it out so I am not sure what it is or where a person could get it. Beside keeping the foam grip clean it made the grip more comfortable to hold. I have a new to me Tejon coming and I want to keep it pretty.
