Big Bertha�is one of the most well-established and iconic names in golf, providing ground-breaking performance that makes the game more fun for players of all abilities.� The new Big Bertha 23 enhances the legacy with a family of clubs precisely engineered to launch the ball high, eliminate the slice, and deliver straight distance. For many golfers, the driver is the most challenging club in the bag and, thus, the biggest obstacle to carding lower scores.� Specifically, a lack of directional control and unwanted, distance-stealing left-to-right spin are often the culprits.� Callaway's unique ability to combine a multitude of exclusive technologies led to a formula that cures the aforementioned ailments.� This potent recipe consists of a forgiving, highly stable club head, a low and forward center of gravity that reduces spin, and a large, forgiving sweet spot. From the generous profile to the high-strength XL Face, the Big Bertha 23 is built to inspire confidence and help you find more fairways.
