See What Our Happy Golfers Are Saying

"For marginal players, this technology will be like the heavens opening up, but even better players will notice the difference right away, as well."

Fairways and Greens Magazine

“I had my son fitted for the GF 4 driver when he had outgrown his little junior set. He is now driving the ball better than he ever has and we are excited to see where he can go with his golf.”

Dan Gleason

“The GF 4 driver is fantastic for the advancing junior who is too strong to play with junior clubs but still needs a head with less weight. With four weight ports and 7 optional screw weights, it is very easy to fine tune the GF-4 to the players swing, giving them the most clubhead speed while maintaining mass in the head.”

Brad Whalen

“The GF 4 is the ultimate driver for extreme fitting. The head without screws is only 183 grams. You can add as little as 6 grams or as much as 48 grams to dial in the exact swing weight for any golfer.”
