Callaway Hawk Eye shaft

wo additional breakthrough designs contribute to the overall performance superiority of the Great Big Bertha Hawk Eye Titanium Metal Woods. The first is our Hawk Eye Sole, first introduced on the Big Bertha Steelhead Metal Woods last year, which pushes the turf down more effectively through impact. The second is the Hawk Eye series of shafts, our lightest, strongest graphite shafts ever. This all-new design features an increased tip diameter providing additional strength and clubhead stability. We've also designed two distinct shafts - one for the drivers and another for the fairway woods, each built to the specific performance requirements of the different clubs.
