Could someone please describe to me how to use distance markers. For example: Royal George hole 10 2nd shot to green. There are 4 distance marker's beside actually distance to the hole. Lower left of screen, distance mark at 104 yards into bunker. Just above that another bunker marked at 111 yards. Now to the right side of the green another bunker distance marked at 101 yards, with the last distance marker at 131 yards to the back of the green meeting rough. Hole distance from drive 124 yards 8 ft up w/tailwind at 20mph.. What does all that mean?
