What you should know before you go and get a driver fitting has become more and more confusing to the average golfer. In this article we will talk about the two main numbers that you need to be concerned with as an amateur.
Launch monitors have really changed the game when it comes to a driver fittings. TrackMan and Flightscope (among other companies) have really given us a new insight over the last five to ten years. As an amateur, the two things that you need to be most concerned about are launch angle and spin rate.
So why should you care about dynamic loft and spin rate? These two factors are the main influences on the height and distance of any golf shot. Let’s talk about both of them…
What Is A Launch Angle
Trackman defines launch angle as the angle that the ball takes off relative to the horizon. When discussing the term launch angle, there are few terms that we need to understand including static loft and dynamic loft.
What Is Static Loft
Static loft is a loft that does not change. The static loft would be determined by the loft of the club that you have in your hand. For example, if you have a pitching wedge in your hand that is 46 degrees then the static loft would be 46 degrees.
What Is Dynamic Loft
TrackMan defines dynamic loft as… the vertical angle of the club face at the center point of contact between the club and the ball at the time of maximum compression. They also add that dynamic loft is the amount of loft on the club face at impact and is measured relative to the horizon. Multiple factors go into determining dynamic loft for each golfer including their attack angle, how the shaft bends, how the golfer releases the club head, whether the club face is opened or closed to the club path and where the ball makes contact on the club face can all affect dynamic loft. Your launch angle will always be a little bit less than your dynamic loft.
What Is Spin Rate
TrackMan defines spin rate as the amount of spin on the golf ball immediately after impact. Typically, the more loft you have to higher the spin rate will be. However, all things being equal the more clubhead speed that is generated the less spin that is needed. Thus, a player with a lower swing speed needs more spin to hit the ball as efficiently as they can.
What Is Angle Of Attack
This will be the bonus term that you should know about. TrackMan defines angle of attack as… the up or down movement of the club head at the time of maximum compression. Attack angle is measured relative to the horizon. As you can see from the chart below, it can also make a big difference in selecting the best driver for you.
So when you are watching golf on Sunday, it is really impressive to see Dustin Johnson, Jordan Spieth or Rickie Fowler come up with a spin rate number in the 1600-1800 range. But, is that right for you? The answer is probably not… Unless… you can generate the type of club head speed.
There are a lot of factors from the driver that you are swinging that go into determining “the numbers.” For example, the driver head that you select can change the numbers. Depending on the head’s size or its center of gravity (COG) these numbers could easily change. The driver shaft variables that could influence dynamic loft and spin rate include the length of the shaft, the stiffness or flex of the shaft, the weight of the shaft as well as the torque of the shaft.
As you can imagine, it is very important to find a trusted Club fitter in your area to get a proper driver fitting. However, once you do find a good club fitter you will be launching your driver high and long.
