Callaway Big Bertha Driver Berthas back, and shes meaner than ever! The new Callaway Big Bertha Driver is so revolutionary, it deserves to carry one of the most legendary names in golf. Its faster and more robust and features Callaways new Adjustable Perimeter Weighting for supreme distance via total driver performance. Hyper Speed Face: The new Hyper Speed face design is nothing short of groundbreaking - its lighter (10% lighter), hotter, and more robust than ever before, increasing ball speeds on shots hit across the face Callaways longest Total Performance Driver Adjustable Perimeter Weighting: Callaway put their new Adjustable Perimeter Weighting slide toward the rear of the club, which leads to significantly higher moment of inertia (MOI) and forgiveness, while offering a wider range of draw and fade bias options. All that amounts to longer, straighter shots 20% higher MOI than Razr Fit Extreme Advanced Adjustable Hosel: Increase or decrease loft in 1 deg increments (up to +2 deg or down -1 deg) with the adjustable hosel to optimize launch angle and backspin for maximizing your distance Adjust draw or neutral directional bias to optimize shot shape even further for more accuracy Forged Composite: High-strength, lightweight crown saves 20-grams of weight, allowing Big Bertha to have Adjustable Perimeter Weighting, a deeper center of gravity (CG) for higher MOI, and low spin with a lighter, more preferred swing weight. The more adjustability you add to a driver, the more imperative it is to have a forged composite construction.
