Callaway Golf's Gravity Core was a big development for the company, bringing it to the forefront of adjustability with a feature that allows players to reposition the driver's center of gravity to offer optimal ball flight and distance.
Adjustable center of gravity has become more commonplace in drivers for better players, so, naturally, Callaway has come out with a new driver that tries to advance the concept.
The company's new Big Bertha Alpha 816 Double Black Diamond driver is built for the lower-handicap player that is looking for additional control of the ball off the tee. In this latest offering, there are now two places in the driver sole where the Gravity Core can be inserted -- spots the company dubs Distance Chambers -- which dictate a draw or neutral bias. After picking the bias, the player can choose to flip the Gravity Core weight up or down, putting the weight behind where the player typically strikes the driver face.
The idea here isn't all about repositioning the center of gravity, but rather put weight where the ball will be hit. However, turning the weight down will reduce spin by some 200 rpm.
This latest version of the Double Black Diamond boasts the company's updated R-Moto face technology, positioning the thin face for maximum forgiveness. The club has a deeper face, positioned slightly open at address, to offer the look better players want. A low center of gravity offers forgiveness. OptiFit adjustability allows for eight positions of loft and lie angle changes.
The Big Bertha Alpha 816 line also updates the fairway woods, offering two adjustable weights (3- and 16-grams) to dictate either less spin with the weight forward or more forgiveness with the weight back. A slightly larger head offers more forgiveness than the typical player's fairway wood.
The Big Bertha Alpha 816 Double Black Diamond driver will hit stores on Sept. 18 and will retail for $500, coming in two loft options (9- and 10.5-degrees). The fairway woods will retail for $300 and come in 14-, 16- and 18-degree options.
