When I got home from hunting last weekend I found a scratch across the screen of my CTX . I know that with regular use things are going to happen but still it bothered me . Then I remembered that I had a bottle of plastic polish that I use to clean cars. So with a little elbow grease and plenty of determination and a bottle of Meguiars Plastx I removed the scratch and the screen looks as good as new . Which brings me to the question .What do you use to protect your detector
