Swing DNA

Shaft Optimizer 3D

Our award winning Bluetooth Shaft Optimizer and Swing DNA software will guide you to your best iron model and shaft combination.

Ask to use the new Bluetooth Mizuno Shaft Optimizer at your local Swing DNA Fitting Centre.

How Swing DNA works

Take 3 swings for the Swing DNA tests

Take 3 swings

Using the shaft optimizer. Strain gauges within the shaft record how you move the shaft. Golfers are generally surprised how consistent their ‘good’ and ‘bad’ swings are. Variation in the result is nearly always down to inconsistency of strike.
Shaft Optimizer

Enter your data into Swing DNA software

Your fitter will take data from your 3 swings of data and enter into the Swing DNA software. The software will align your unique DNA with a map of custom shafts independently measured and assessed by Mizuno.
Rank Shafts

Rank every shaft for suitability

Our Swing DNA software will rank every available iron shaft (based on their EI curves) as best to worst theoretical match against your swing profile. The new software shows every available shaft in order of suitability.
Test your recommended shafts

Test the recommendations

Your Swing DNA shaft selection is based on science. After hitting the recommended options your fitter will be able to show you real world distances and dispersion. You may decide to promote a lower ranked shaft based on feel and sound. You may even prefer a non optimal flight that suits your eye. You make the final decision.

TXG Shaft Optimizer 3D In-depth Analysis

"Love this video! Was wondering if my 6.0 was to stiff for my numbers but the second swing was spot on my swing speed, release and shot shape. Thank you guys!"

“Went for a Mizuno fitting with my Pro, who is also a Master Fitter. He "didn't need" the Optimizer to select my proper shaft. I struggled for 30 minutes with three different heads to hit solid shots. Then I insisted on employing the optimizer, which suggested three shafts the Pro thought would never work for me. A month later, I have a new set of 919s with a shaft suggested by the optimizer and new Pro!”

“My 85mph swing was Tempo 5, Toe Down 4.25, Kick 2.5 and Release 2.0 - recommended shaft was Dynamic Gold S300 120, Project X 5.5, Project X LZ 5.5 and Flat -0.5 - which is basically spot on. ”

“I walked in the the Mizuno store in Atlanta and got optimized. I am 57 and had been slowly moving into regular flex, trusting the pro recommendations. The Optimizer put me into Extra Stiff and my dispersion went from Tennis Court to Service box. I'm a believer.”

“Been a Mizuno Fitting Centre for many years. The new 3D Optimizer is a brilliant fitting tool. The Lie Angle measurement takes away the inconsistent readings that you often get with a lie board. Great video well done.”

“I have been on the previous version of this and I narrowed down my favourite shaft of the 3 that it suggested and I then proceeded to have 2 other manufacturer fittings end up in the same shaft after a longer process.”

What Do We Measure?

The Shaft Optimizer measures 5 elements of your swing. Club head speed alone doesn’t dictate which shaft should be most effective for your swing.

Luke Donald
  • Clubhead Speed

    How fast the clubhead and shaft are moving during the swing.

  • Tempo

    How quickly the player transitions from the backswing to the downswing.

  • Shaft Toe Down

    A measure of the bowing of the shaft in a downward direction during the downswing.

  • Shaft Kick Angle

    The amount of shaft forward bending during the downswing motion.

  • Release Factor

    How and when the clubhead and shaft are releasing during the downswing motion.

Player DNA - Average Optimizer score

Tour Player Swing DNA

Our DNA software suggests 3 best matched shafts to test - but there are also human factors (eg: feel) that can override the recommendations. The final decision is always down to the player.
