GT D-617 α-SPEC Driver

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.

Geotech is proud to introduce the all new GT D-617 α-SPEC driver for 2017. The GT D-617 is designed to help the player make better contact by squaring up to the ball more consistently for more efficient energy transfer and increased ball speeds. Better players sometimes struggle with the head squaring too quickly causing pulls and hooks. This NON-conforming model features a variable thickness DAT55 face which creates even more spring effect. The GT D-617 center of gravity is optimized to focus on squaring to the ball and grabbing the ball with maximum energy for more distance and a straighter trajectory. The next generation GT Series with more ball speeds than ever is here now!

HIGH REPULSION DAT55 FACE INCREASES BALL SPEEDS!

HEAD DESIGN SQUARES TO THE BALL FOR MORE REPULSION!

SUPER DISTANCE WITH LOW SPIN!

OPTIMAL TRAJECTORY WITH LOFT & LIE ADJUSTMENT!

3HIGHER BALL SPEEDS + LOW SPIN

Ultra high rebound head with high repulsion performance and great impact feeling are simultaneously achieved by utilizing a new DAT55 Titanium face for a larger sweetspot and increased performance over the previous model.  The center of gravity is designed to square more consistently to the ball at impact, increasing initial ball speeds by maximizing energy transfer. The CG placement also results in lower spin, with a 4.6% lower center of gravity than the previous model. The best trajectory can be achieved thanks to a wider variety of lofts (9.5 to 11.5 degrees) which help increase the launch angle. This balances out a common issue low spin drivers sometimes have of too little spin. High launch, higher ball speeds and low spin create more overall distance.

SHORTER CENTER OF GRAVITY = HIGHER OPERABILITY

By designing the head with a shorter center of gravity (33.9mm), stability and operability are increased. Shortening the the center of gravity also makes it possible to reduce the club’s moment of inertia which helps make the club easier to swing and handle.

OPTIMIZED TRAJECTORY

An all new adjustable hosel adapter allows players to adjust the loft and and lie angle, making it possible to adjust the trajectory of each player’s ball flight.  This can be extremely helpful with changing conditions meaning players can adjust their club based on variables such as weather and wind the day of their round.

NEW VARIABLE THICKNESS FACE

Designed to work in synergy with a shorter center of gravity design, the new variable thickness face has been redesigned by changing the thickness around the heel area to increase the sweet spot and improve overall distance.

VARIABLE WEIGHT DESIGN

In addition to the standard 12g weight, optional 4g, and 8g weights are also available. This allows users to alter the overall club length and match swing weight properly without effecting swing feel and performance.
