The GT PROTO 420 SHALLOW driver, a shallow type model, has been added to the lineup of the popular GT1. Although it has the same head volume as the GT1, the shallow model design gives it a crown projection area that gives a sense of security and does not make the head size feel small when addressing the ball.

The head performance is high maneuverability and strong feeling of pushing the ball, which are the characteristics of a 420cc head. In addition, this model is equipped with a 15g stainless steel power plate. This achieves a low center of gravity and suppresses the increase in unnecessary backspin that is common in shallow models.

The new model GT PROTO 420 SHALLOW is born, adding forgiveness to the flight and maneuverability of the GT1.
