This site is for the golfer that wants to understand golf shafts. When I entered the golf club fitting business, I learned that there was no standard rating system for golf shafts. That was and still is a problem for fitting golf clubs. Creating a uniform system was possible, it just had not been done. I learned what I could from golf shaft engineers, purchased the instruments that were available and invented my own EI instrument. It took a few years to refine the EI Instrument and many, many years to acquire and measure the popular golf shafts. This site provides uniform measurements of thousands of golf shafts.

If you are new to this site, the technology menu is a collection of articles that will help you understanding golf shaft design and the attributes of the golf shaft that can be independently measured. My objective in creating this site is to balance the marketing messages of the golf business with some science. And ultimately, help you make better decisions when selecting your golf clubs.

This video is a detailed discussion about golf shafts stiffness and the history of how it was measured and marketed.

It took years to understand shaft measurement and many more years to accumulate a meaningful database of shaft measurements. The magnitude of that accomplishment did not occur to me until a golf shaft company owner said it to me. Several golf shaft companies now use the EI measuring instrument I designed and manufactured. This video is a discussion with three other Top 100 fitters about how having a shaft database changed their business.

If you believe as I do that the golf shaft is essential to good golf, register now. Testing shafts and writing articles takes a great amount of time. The membership fee underwrites the time and resources needed to keep this site going and growing. It also funds the acquisition of shafts that have not been available. You will notice, this site is does not run ads, that allows me to remain unbiased in the articles.

If you are a golf professional and would like access to more data there are two choices. Golf Professional subscribers get access to a larger set of data and individual profiles of all the shaft model weights and stiffness variations that were made available. Fit2Score Affiliates have access to the entire database through Excel. To hear a recent podcast interview I did about golf shafts with Tony Wright, a Fit2Score Software Affiliate, Click Here.

I have started producing and publishing the 2020 PGA Merchandise show videos on my YouTube channel, Devoted Golfer. The videos were shot at the International ClubMakers Guild meeting.
