Geotech's GT Series has always represented the best in design and technology from our brand. It's performance oriented enough for the better player, but also offers enough ease of use for the improving golfer. It's the all around lineup for a wide range of players who don't want to cut corners when it comes to performance.

GT BLACK RENEWAL! The GT 455 Black was released back in 2008 and became known as the the distance model the GT Black series - it did this by utilizing a heavier 203g head in order to create the sweet spot and spring effect needed to achieve max distance . The newest GT Black models inherit the bloodline of of older GT Blacks and take performance to a new level by injecting new technology and manufacturing techniques. This allows the new GT Black to achieve improved distance performance with a head weight of only 196g. With the lighter head weight comes the possibility for longer club lengths, an easier to swing club and realization of increased head speed and more overall distance.

This high launch is part of the three elements of distance created by the GT Black, high initial ball speed, high launch and low spin. Maximum distance achieved.

CENTER OF GRAVITY ACCORDING TO SWING TYPE

The GT Black features interchangeable GT Stabilizer Screws which allows each golfer to adjust the center of gravity depending on their swing type or desired trajectory.
