The shaft characteristic becomes clear, before measuring three carbon shafts for golf,
analyzing the correlation of the hardness of each part and assembling as a golf club.
Please find the golf shaft suitable for yourself and realize a score rise and a driving distance rise!

150 mm of both 250 mm (chip rigidity), a center (center rigidity), and a grip back end to 250 mm (bat rigidity)
supports of three points each are fixed from a tip, and the three points are weighted at a golf shaft, respectively.
In order to bend 2 mm, it measures the weight of what kg is required.

The value of the value Butt of the value Center of Tip is measured,
and this how that it is soft and a shaft comes to carry out is calculated and displayed.
In inputting the measurement value of three points using the method of analysis of
the golf shaft called what is called three-point rigidity distribution, a C/B value, a T/C value,
and a tune coefficient are calculated automatically, and the motion image of a shaft is displayed.
AB map is carried and an input result is displayed as a yellow star mark.
Moreover, Trialphas (pink) and YardStick (red) are displayed.

Display printing of the measurement shaft data of GraphiteDesign (green), FUJIKURA (cian),
and Mitsubishi (Orange) is carried out by depressing 50g, 60g, and a 70g button.

* As for each measurement data, Yardstick, Inc. (http://www.yardstick.co.jp/) uses shaft rigidity measuring instrument
YG-110 (http://www.yardstick.co.jp/products/yg-110.html). The measured shaft data is used.

* Since the same maker's same model and hardness are also with error
for every shaft simple substance, secure no measuring results.
Please think as a standard.
