on either side of the sweet spot (dinger) are two blue areas the light blue one right next to the dinger the dark blue one further out. to fade or draw drag the marker to the opposite side of the direction you want to go. if a draw drag it right, if fade drag left. then you want to hit the ball no more than 1/2 way into the dark blue area from the outside edge (furthest from the dinger)....1/4 is ideal.....more than 1/2 on the draw or less than 1/2 on the fade wont curve it enough. the further from the dinger you hit the more it will bend. light blue area will just hit straight to the side.
i use this on bethpage # 2 all the time.
