Professional Golfer, World Golf Hall of Famer, Sandy Lyle describes our board on the Golf Channel as being one of the must have tools of the trade. He uses our board as a training aid to demonstrate how he changed his swing to hit a perfect draw. PGA Champion, Mark Brooks has used the board for two years as well and he believes that our board paints a picture of a perfect swing path. For Mark it has become one of his "go to" tools to correct and perfect his swing.
