What you need To know before buying a Driver.

A good golf instructor that understands golf club fitting is worth their weight in gold.  Fitting clubs is not a perfect science however technology has made club fitting better.  Before the Launch Monitor, a club fitter would watch the ball flight on the range with many different drivers to find the correct loft and shaft.  With the Launch Monitor it gives the fitter some statistics to better fit the driver before trying them on the range.  Even with the Monitor, I still find some players needing a different club on the range.  This is where a good eye and understanding of  the golf swing can help.

The fitter will ask many questions about the player since all information can help find the correct driver.  It is similar to a puzzle.  You need all the pieces before putting it together.  Some of the information  that is needed in conjunction to seeing the swing is:

Age
Practice Time
Playing Time
Do You Take Lessons
What Are Your Goals
Ball Flight
Current Distance of Driver
Ball Height
Swing Speed
Tempo
Angle of Attack
Path of Club
Face Angle
Hand Size
Any Health Issues (for example:  injury, arthritis)

What it comes down to, is still hitting demonstration drivers and having someone getting all the information to better fit you.
