Callaway Golf Introduces Hawk Eye(R)
Tungsten Injected Titanium Irons

In a technological breakthrough designed to help golfers take control of their iron shots and inject more fun into their games, Callaway Golf Company announces the introduction of Hawk Eye Tungsten Injected Titanium Irons.

Each of these revolutionary new irons is injected with the exclusive new Callaway Tungsten Weight Matrix, a heavy mixture of tungsten and other metals that creates a precisely placed, extremely low center of gravity to help golfers hit shots with optimum trajectory and maximum forgiveness.

Created as the premium companion to the best-selling Great Big Bertha(R) Hawk Eye Titanium Woods, the Hawk Eye Tungsten Injected Titanium Irons also are loaded with the superior design features and playability benefits that golfers worldwide have come to expect from Callaway Golf. The new Hawk Eye Tungsten Injected Titanium Irons are now available in select golf shops across the country, replacing the Company's previous line of Great Big Bertha Tungsten*Titanium Irons.

Designed by Callaway's Senior Executive Vice President and Chief of New Golf Club Products Richard C. Helmstetter and his team, the Hawk Eye Tungsten Injected Titanium Irons have a number of significant new design features. Each Hawk Eye Iron is cast from titanium with an interior weight cavity that runs inside the length of the clubhead's sole and extends upward behind the center of the clubface. Small, uniformly sized tungsten spheres are placed low and deep in the weight cavity, which is then injected with a dense molten metal. This molten metal surrounds each of the tungsten spheres and locks them in place as the mixture cools, melding into our exclusive Callaway Tungsten Weight Matrix.

In a Hawk Eye 5-iron, the super heavy Callaway Tungsten Weight Matrix constitutes only 27 percent of the clubhead's volume while accounting for 45 percent of its weight.

"In the modern game, in irons, control is what you want," Mr. Helmstetter said. "You want the ball to hit and stop, not hit the green and roll like a driver. The Hawk Eye Irons were designed to produce that trajectory, flighting the ball high and landing soft. This is a direct result of using the Callaway Tungsten Weight Matrix to create a substantially lower center of gravity in these irons compared to any other irons we've ever designed.

For example, the Hawk Eye 5-iron has a center of gravity that is approximately 24 percent lower than both the Great Big Bertha Tungsten*Titanium and Big Bertha X-12(R) 5-irons. And because the weight is spread across the sole of the club, there's greater resistance to twisting on off-center hits for added forgiveness.

" The Callaway Tungsten Weight Matrix allows Callaway Golf to position the center of gravity in the best possible location in each of the Hawk Eye Tungsten Injected Titanium Irons. In the long irons, the Callaway Tungsten Weight Matrix creates the lowest center of gravity in any iron design in the Company's history to help create a high ball flight. In the short irons, the Callaway Tungsten Weight Matrix is fine-tuned to provide a slightly higher center of gravity to enhance control and optimize trajectory.

As with every new Callaway Golf product introduced since the Company first revolutionized the industry with the original Big Bertha(R) Driver, Hawk Eye Tungsten Injected Titanium Irons have been designed to be demonstrably superior to, and pleasingly different from, any comparable golf club on the market. Hawk Eye Tungsten Injected Titanium Irons conform to United States Golf Association Rules.

"We are going to great lengths to illustrate the benefits of our new Hawk Eye Irons to consumers and the trade," said Bruce Parker, President of Callaway Golf Sales Company.

"These irons present a challenge to us, because even though they are by far the best-performing titanium irons we've ever made, the lion's share of the technology involved is hidden inside the clubhead, and is therefore not visible. We are confident that once golfers hit the Hawk Eye Irons, they will easily see and feel the performance benefits we have built in."

Other design features of Hawk Eye Tungsten Injected Titanium Irons include a new sole design and an elegant new look for the clubhead. Hawk Eye Irons feature a four-way cambered sole to help reduce digging on shots from the fairway. This feature also helps the clubheads to glide more easily through thick rough and sand.

Golfers will also notice the striking, more traditional appearance of the Hawk Eye Irons, including a sandblasted face and a thinner topline. Of course, Hawk Eye Tungsten Injected Titanium Irons also include proven Callaway Golf design features such as S2H2(R) (Short Straight Hollow Hosel) and Tru-Bore(R) Technology for unmatched perimeter weighting and feel. Hawk Eye Irons also utilize the patented 360-degree variable undercut channel to help move weight toward the perimeter of the clubhead for solid feel on every shot. Hawk Eye Tungsten Injected Titanium Irons are available in 1-iron through 9-iron with pitching, approach, sand and lob wedges.

The complete line of Hawk Eye Irons will be available in both right- and left-handed models, as well as Ladies' Gems. Shaft options include the new Hawk Eye Graphite series in light, regular, firm and strong flexes, Ladies' Gems Graphite, and the Hawk Eye Steel uniflex shaft. The suggested retail price for the new Hawk Eye Tungsten Injected Titanium Irons with graphite shafts is $1,249 for a set of eight. Hawk Eye Tungsten Injected Titanium Irons are available in selected retail shops across the country.
