The new Callaway Great Big Bertha Driver is designed to get the most distance for ALL golfers. This driver is a technological breakthrough that includes a multi-material aerodynamic shape and a sliding weight so that you leave no yard behind.
New for 2015 is the AF-303 which fits in very nicely between the AF-302 and the AF-503. A much wider sole and a slightly thicker top line when compared to the AF-302. When compared to the AF-503, the new 303 has slightly weaker lofts, less offset and a thinner top line.
