...first ensure that decent contact is being made between the ball and the driver face

In order to maximize distance with the driver, we have to first ensure that decent contact is being made between the ball and the driver face. Before hitting, spray some foot powder spray on your driver face to determine where you are making contact. For most golfers, the optimal spot to make contact is on the upper middle portion of the driver face. Once consistent contact is being made, then you can work on adding club head speed.
