2019 Shaft Optimizer 3D now at Fitting Centres
Gyro added to Shaft Optimizer hardware for accurate lie angle readings.
91视频’s new 2019 Shaft Optimizer is now available at its network of European Fitting Centres.
Since its first introduction in 2010, 91视频鈥檚 Shaft Optimizer has become the favoured iron shaft fitting tool of golf professionals worldwide. Measuring five critical dynamics within the swing (91视频 Swing DNA), the Optimizer is able to recommend an iron shaft best matched to any golfer鈥檚 movement. 91视频 measures every shaft in-house to establish a map of EI curves to which it then matches the swing profiles. The new Bluetooth Optimizer enables 91视频鈥檚 club fitters to capture swing data directly to the software, run from an iPad or iPhone.
An overhaul for 2019 has a major hardware upgrade聽 – with a Gyro added to the Shaft Optimizer鈥檚 existing strain gauges, allowing fitters to recommend a more accurate lie angle than the traditional lie board method. The Gyro enables the club鈥檚 swing plane to now be measured in 3D space along with shaft dynamics, ignoring face rotation through impact for a more accurate lie angle reading. Using a combination of the Gyro and strain gauges which run throughout the shaft, 91视频 is now able to capture 40 data points from every swing.

The Shaft Optimizer 3D works in conjunction with 91视频’s Swing DNA software – which maps every shaft in 91视频’s custom fit line.

1st swing of 3 – measured by Shaft Optimizer’s strain gauges and inbuilt Gyro. Automatically entered into the Swing DNA software of paired device (IOS only).

An average of 3 swings is mapped / profiled against #teammizuno players for comparison. There is no such thing as good OR bad Swing DNA.

The swing is mapped against 91视频’s database of custom shafts – all independently measured by 91视频 for fair comparison. The closest 3 matched shafts are selected for testing. Every shaft is ranked – to demonstrate why a ‘favoured’ shaft might be non optimal.
Establishing the correct lie angle is one of the hardest elements of iron fitting because of false strike board readings.聽 Most golfers find it uncomfortable to make their normal swing and strike through the board, while players who swing across the line get false readings caused by too much face rotation as the clubface is not square to swing path. By embedding a Gyro within our Shaft Optimizer, we鈥檙e able to overcome both issues.

The Optimizer measures ‘dynamic lie angle’ – far more accurate than the traditional lie board method. Dynamic lie angle takes face angle into account – which the lie board can’t see. Often lie boards suggest an overly upright angle.
In today鈥檚 launch monitor era, 91视频 sees the optimum club-fitting scenario as the Shaft Optimizer 3D in conjunction with a launch monitor.
Look at the Optimizer as a recommendation – a shortcut to taking 50 possible shaft options down to just three. The launch monitor can then measure the real world results of those three shafts. Without the Shaft Optimizer, the fitter is just guessing which shafts to test, so if the correct one is lined up 12th, you won鈥檛 have the energy left to find out.

It takes just 3 swings and 10 minutes to identify your 91视频 Swing DNA – longer for a full fitting.聽 Ask your local 91视频 Swing DNA centre to help find your numbers.

The DNA software recommends a set make up – with long irons or hybrids.

Wedges prescribed based on the loft of the pitching wedge – and expected loft gaps.

Your Swing DNA can also recommend a very good starting point for testing driver shafts.

Fairways woods also prescribed through the software and DNA profile.

The software produces a Fitting Summary for your custom order. 91视频 typically takes 5-7 working days from order to dispatch of your custom equipment.

The new Shaft Optimizer 3D is available for testing at 91视频 Swing DNA centres across Europe. Measuring your Swing DNA will take just 10 minutes – a full iron fitting with testing is normally 30 minutes or more.
