The Great Big Bertha(R) II 415 Titanium checks in at 415cc in clubhead volume. That's not huge by today's standards, but it is the largest driver head Callaway has brought to market, and is a significant increase over the 380cc of the original Great Big Bertha II driver.
Callaway says the new GBBII 415 is the most forgiving Great Big Bertha ever.
"The Great Big Bertha II family of titanium drivers and fairway woods has been very well received in the marketplace over the past year," said Ron Drapeau, Chairman and CEO of Callaway Golf. "By adding the new Great Big Bertha II 415 Titanium Driver to the lineup, we now offer an exciting option to golfers looking for a Callaway Golf driver with a larger clubhead and more forgiveness."
Callaway says its engineers have used the extra 35cc of volume designed into each Great Big Bertha II 415 Titanium Driver to increase the driver's Moment of Inertia (MOI). A higher MOI means the clubhead is more stable at impact.
The Great Big Bertha II 415 is designed to provide consistent ball speed, backspin and launch angle on shots struck across a large area of the club, which helps minimize any losses in distance or accuracy on off-center hits. The club provides the maximum coefficient of restitution (COR) allowed.
The new Great Big Bertha II 415 Titanium Drivers utilize the same proprietary series of high-performance graphite shafts that have generated positive feedback in the original Great Big Bertha II Titanium Drivers. The GBB System 60 and GBB Gems 50 shafts are lightweight, low resin-content graphite shafts with high strength and responsiveness. The GBB System 60 graphite shaft is a 45-inch shaft available in Light, Regular, Firm and Stiff flexes, while the GBB Gems 50 is a 44-inch ladies flex shaft. Great Big Bertha II 415 Titanium Drivers are also available with four of the most popular after-market shafts - the Aldila Green NV 65, Grafalloy ProLite 35, Graphite Design YS-6 and Fujikura Vista Pro 70 - factory-installed at no extra charge.
The new Great Big Bertha II 415 Titanium Driver is available in three lofts for right-handed golfers (9, 10 and 11 degrees) at a suggested retail price of $500.
A version of the Great Big Bertha II 415 Titanium Driver that exceeds the limits on COR enforced by the USGA will be marketed outside of North America. This driver, the Great Big Bertha II 415+ Titanium Driver, has a hot face that exceeds the 0.830 limit on COR and is conforming for use in non-tournament rounds outside of USGA jurisdictions.
