stupid? lol. dude, it's a cool toy. it's not going to help my swing but it will help a lot with proper club selection,it'll give me the distance to all the bunkers,hazards. and it'll show me where the green is when you can't see it.more importantly,i'd rather know where the green starts and ends,yardage wise,than to know where the actual pin is. all i have to do is glance down at my golf cart.
and check it out for yourself,especially the Intelligreen feature: (move your cursor to represent your ball location)
