September 29, 2014 – Callaway Golf wants to give golfers an unprecedented opportunity to unlock ‘up to two clubs longer’ distance from their shots with the announcement of super-forgiving, super-long Big Bertha Irons.

Heralding a new generation in ‘fast’ performance, the all new cast, hollow-bodied head design features a wrap-around 360 Face Cup which marries the ball speed benefits of Callaway’s Variable Face Thickness (VFT) Technology to a Cup Face construction that spreads the sweetspot across the whole hitting surface.

To maintain forgiveness and maximise ball speed, Big Bertha Irons feature an Internal Standing Wave design that pushes the centre of gravity low and forward in the head, allowing the ball to get airborne easier and with increased MOI at impact (resistance to twisting), meaning more shots on target.

Dr. Alan Hocknell, Callaway’s Senior Vice President of Research and Development, said: “We are significantly raising the bar of what’s possible in the design and performance of irons with the introduction of Big Bertha.”

“We’ve taken proven Callaway Driver and Fairway Wood technologies – VFT, Face Cup and the Internal Standing Wave concept – and configured them for irons. The result is a new generation of ‘long’ that not only delivers blistering performance out of the sweetspot, but also maintains it across the whole face, which is great news for golfers of all abilities.”

First Callaway adjustable utility clubs
For golfers that consistently struggle with their long irons, Callaway also announces its first-ever range of adjustable utility clubs – Big Bertha Hybrids. Like the Big Bertha Irons they are longer and built for huge ball speed, but with adjustability for even more distance and control.

The hybrids feature Callaway’s Speed Frame Face technology which is thin, light and robust so that it is fast across the whole club face; this is where the fast ball speed comes from. Coupled to this, an Internal Standing Wave inside the head lowers the CG, ensuring the golf ball launches quicker, forgiveness is maximised, and the club’s high resistance to twisting on impact (MOI) is maintained, ensuring pinpoint accuracy.

To help create the ideal trajectory, an adjustable OptiFit hosel has been added, giving golfers the opportunity to choose from a combination of eight different loft (-1, S, +1, +2) and lie angles (draw and neutral) to really dial in shot shape.

Dr. Alan Hocknell said: “For the first time, we’re bringing adjustability to our hybrids and the new Big Berthas are leading a whole new level of performance capability for the category. They generate incredible ball speed across the face, and with the adjustability feature delivers a really versatile club that’s easy to launch.”

Big Bertha Irons feature premium shaft options as standard – either True Temper Speed Step 80 steel or a new UST Recoil graphite and are available for men and women, in right and left-hand options. At retail from 17th of October.

Big Bertha Hybrids are available in: 3-hybrid (19°), 4-hybrid (22°), 5-hybrid (25°), 6-hybrid (28°), 7-hybrid (31°) (some options custom fit only). At retail from 17th October.
