Callaway Great Big Bertha

Most golfers aren't very good at getting the most from their tee shots. This driver is designed to improve three things golfers struggle with: ball speed, launch angle and direction. First, a thin, lightweight face keeps mis-hits from losing too much speed. Second, the lightweight construction, including a composite crown, keeps the center of gravity low to help shots launch with less spin. The head also accommodates 19 custom shafts as light as 40 grams to maximize clubhead speed. Third, a sliding 10.5-gram weight in an aerodynamic channel in back makes left or right misses more playable.
