The Bombtech 4.0 Driver and 3 Wood is here to give you more confidence off the tee. The original dual cavity design was engineered with the University of Vermont capstone project. This aerodynamic design was created to break up the airflow and reduce drag. With a bigger 460cc, the BombTech 4.0 driver gives you even more confidence when stepping up to the tee. We strategically moved the heel and toe weights to be internal to further improve sound and feel. The shaft is now sitffer by nearly 5cpms. The end is result is a BIGGER, STIFFER driver that reduces mishits and lowers spin.
