Mizuno SHAFT OPTIMIZER User Manual

USER GUIDE
Choosing the right shaft for your customer is one of the most important aspects of Club Fitting. Since the shaft
will affect distance, ball flight, spin and trajectory, this portion of the fitting should not be overlooked. Fitting
the shaft is not as simple as reading clubhead speed. For a complete and accurate fitting, the fitter should
consider all of the following factors:
Club Head Speed: How fast the club head and shaft are moving during the swing.
Tempo: How quickly a player transitions from the backswing to downswing.
Shaft Toe Down: A measure of the bowing of the shaft in a downward direction during the down swing.
Shaft Kick Angle: The amount of shaft forward bending during the down swing motion.
Release Factor: How and when the club head and shaft are releasing during the downswing.
Two players with identical club head speeds and tempo can require two totally different bending profiles
based on their shaft toe down, shaft kick angle and release factor.
The Mizuno Shaft Optimizer allows the fitter to measure club head speed, tempo, shaft toe down, shaft kick
angle and release factor during his/her swing while hitting a golf ball. By measuring club head speed and
tempo you can determine the ideal flex and weight of the shaft. These two measurements along with shaft toe
down, shaft kick angle and release factor indicate how the shaft is bending during the swing.
Taking all these numbers into account will allow the Shaft Optimizer software to recommend the ideal shaft
bending profile which will deliver maximum consistent energy transfer to the ball.
Fitting the right shaft requires experience and some trial and error. However, by using the Shaft Optimizer it
should give you an excellent starting point in the shaft fitting process.
