Through 'Digital Impact Technology' the all titanium Srixon W-403 AD driver offers optimum deformation charactersitics through its 'Impact Power Body'. At the point of impact the entire body deforms to provide a high launch angle. The face hugs the ball longer resulting in reduced spin, and a higher transfer of energy. A huge elliptical sweet spot provides stable distance on off-centre hits, even on those days when you are not on top of your game. Srixon 403 AD driver also features the 'Auto Turn Design' in which the centre of gravity in the lower lofts is placed towards the toe and moves progressively back to the heel in the higher lofts. Thanks to the optimized relationship between head speed and loft, the Srixon 403 AD is the best driver for the widest range of golfers. With Srixon's 'High Power Weight' the rear portion of the sole has been made thicker from toe to heel. This extra weight gives the lowest centre of gravity position among 420cc big head drivers.
