What is measured

Here are some general ideas of what your clubfitting expert will measure. Not all measurements are included at all fitting locations.

CPAS (Callaway Performance Analysis System) uses high speed optics to accurately capture club/ball dynamics before, at, and after impact. The captured ball launch conditions are used to simulate the ball flight within our Virtual Test Centre software.

• 

  Clubhead speed

  This is a measurement of how fast the clubhead is travelling at impact. Clubhead speed will help determine shaft flex, shaft weight and even loft during the fitting. The faster the clubhead speed, the more potential for ball speed.

• 

  Ball speed

  Ball speed informs the club fitter how fast the ball leaves the clubface and if the player is making good contact. The higher the ball speed, the more the ball’s Centre of Gravity (CG) and the club’s CG are in line at impact – i.e. how well the player is striking the ball.

• 

  Attack Angle

  This is the measurement of how steep the clubhead is travelling at impact with the ball. This can affect the spin characteristics and launch angle. Choosing the right clubhead in terms of models, loft and offset, as well as the right shaft, relative to a player’s swing characteristics is essential to maximise launch conditions.

• 

  Launch angle

  This is the angle relative to the ground when the ball leaves the clubface. Launch angle is crucial information for fitting a player into the correct loft. The ideal launch angle combined with the proper amount of back spin will maximise carry distance.

• 

  Side angle

  This is a measurement in degrees of where the golf ball starts relative to the target. Side angle is primarily used when fitting (for drivers) for face angle and Centre of Gravity (CG). Face angle is the measurement of how the club sits at address (open, neutral or closed) and CG is the weighted bias of the club (Neutral or Draw).

• 

  Back spin / Side spin

  Spin rate of the ball is measured in RPM’s. Back spin is what lifts the ball and keeps it airborne. Not enough back spin will cause the shot to drop out of the air and will reduce carry distance. Too much back spin will cause the shot to balloon, reducing carry distance and roll. Side spin is a measurement of how much left or right spin is imparted on the shot and indicates whether a player is drawing/hooking or fading/slicing the ball.
