Callaway unveil new Big Bertha Alpha 815 driver duo
Published: Last updated:
Following the Big Bertha V Series launched in August, Callaway completes its trio of Big Bertha drivers for 2015 with the Big Bertha Alpha 815 and Big Bertha Alpha 815 Double Black Diamond.
The original Alpha was geared towards better players, but the updated model comes in two versions to fit a broader range of abilities. Callaway has retained its Gravity Core technology, which alters the centre of gravity location, in both new drivers.
“We found from research during fittings that not only did golfers use the Gravity Core to change the spin, they also used it to get the heavier end more behind their impact location on the face to boost ball speeds,” Alan Hocknell, Callaway’s Head of R&D, told us.
Details: Standard BB Alpha 815 RRP £379, Double Diamond £399. Available from November 14 in 9°, 10.5 and 12° (standard BB only) with a 53g Fujikura Speeder Motore 565 shaft as standard. A matrix of 14 stock shafts is available with no upcharge.
