The Boccieri Golf Heavy Driver with 9-degree loft is a golf club designed with a focus on stability and control through a unique weighting system.

Here's a breakdown of its features and benefits:

Design Philosophy: The Boccieri Heavy Driver incorporates counter-weighting in the butt end of the shaft (a 50-gram backweight) combined with a slightly heavier clubhead compared to traditional drivers. This design aims to raise the balance point of the club, theoretically leading to a more consistent and repeatable swing.

Head Construction: The driver features a 460cc 6-4 titanium head.

Dimple Face Technology (DFT): Boccieri's proprietary DFT involves an internal dimple design on the face, similar to a golf ball. This technology aims to maximize the coefficient of restitution (COR) and coefficient of thermal expansion (CT) for increased ball speed, while maintaining durability. It also helps redistribute weight from the face to the clubhead for a higher moment of inertia (MOI) and a larger sweet spot.

Shaft: The driver is typically equipped with an Aldila NVS Graphite shaft. The 9-degree model may be available with a Regular or Stiff flex

Reported Benefits: Reviews suggest the heavier feel may help slow down the backswing and promote a smoother transition and more controlled swing plane. Some users reported improved accuracy and a solid, powerful feel at impact. One review noted the 9-degree version provides a lower trajectory and more roll out.
