I went over to a golf shop to look at my swing. When I was done the guy said why are you here? I was hitting the ball great, but on the course i lose distance. I had the 7 iron going 150-155. On the course i can only get 145 or less. I'm always chipping on. What's with that? Is the mat helping with distance. I know the mat helps ball flight, but i din't think it helped with distance. I'll have to do lessons right at the course from now on.
