Tour + Tubby

  - Diamond Tour Golf
The Tour + Tubby titanium driver, which utilizes Square Technology, is designed to increase driving accuracy. This technology works by moving the weight further back on the driver and closer to the heel and toe, thus the square shape. This means that if you hit the ball on the toe of a higher MOI (Moment of Inertia) driver the driver will twist less at impact and the ball will wind up closer to the intended target than it would have with a similar strike off a lower MOI driver.
