Callaway Golf Company has announced the launch of its new X Hot and X Hot Pro irons, which are designed to deliver increased distance and performance for both amateur and professional golfers.

Callaway’s award-winning Research and Development team has incorporated a Deep Undercut Cavity Design and Speed Frame Face Technology into the irons, resulting in improved distance, feel and ball speed.

The undercut design has allowed engineers to precisely position the centre of gravity, moving the hottest part of the face lower down to the area where most golfers connect with the ball.

The speed frame technology – previously employed in Callaway drivers – is also making its debut it the X Hot irons.

This technology creates more efficient energy transfer by optimising face stiffness, which helps facilitate increased ball speed and consistent distance, even if the ball isn’t struck out of the club’s sweet spot.

“The X Hot Irons have been meticulously engineered – both in terms of physical characteristics and club configuration – to increase ball speed and promote overall distance optimisation,” said Dr. Alan Hocknell, SVP, Research and Development, Callaway Golf.

“And in doing so, I think we have raised the bar and created the standard in distance for the irons category. Golfers will very much enjoy the results.”

The X Hot irons also feature Feel Management Technology, which fine tunes sound by promoting a crisp, dynamic feel.

The X Hot Pro irons, created with the lower-handicap golfer in mind, combine explosive power, feel and accurate shot-making.

They possess J-Face Dynamics for great power and feel, and Callaway’s most precise 20-degree Close Spaced V Grooves, which offer more backspin from the rough.

Callaway has also announced the release of X Hot and X Hot Pro hybrids, designed to complement the distance-promoting long irons.

They both give faster ball speeds, greater manoeuvrability from a variety of lies and the distance and forgiveness of a fairway wood with the accuracy and control of an iron.

The X Hot Hybrid will be available in 3,4, 5 and 6 models, with the X Hot Pro purchasable in 16-, 18-, 20- and 23-degree lofts.

Callaway’s new clubs will be available to buy from January 25, 2013.
