                                                         History of Shaftuner                

                                           

My name is George Hodgetts, the author of the book  Match Your Driver to Your Favorite Club and the founder of Shaftuner, assembled this web site to reach a wider audience  than local golfers. The beginning of the technology on which the company is based, started around 1977  when I received a catalog from a company named “Golf Day Products”.  By 1980, I learned that a strobe light and a grip vise could be used to accurately determine the flex of a shaft. Being an electrical engineer, I was able to build a crude golf club frequency meter to measure the flex of my set of clubs.  Their flexes were erratic so I re-shafted my entire set so that their flexes progressed evenly from club to club  on a club length-frequency chart recommended by True Temper.

Of course, I had no way to determine what overall flex I needed in the first place, but at least all my club’s flexes were “frequency matched” to each other causing an immediate drop in my handicap. Many years latter I would develop a method for testing players with test clubs that identified the exact “best” flex for each individual and a better method for matching clubs in a set than the straight line method recommended at the time.

In 1983, a PGA touring pro named Rex Caldwell came to Pleasant Valley in Sutton, MA, to play the annual PGA tournament, after missing almost all the cuts for the previous three months due to a broken driver. In  an article appearing in the Boston Globe , he claimed he had tried 15 drivers to replace his broken one, without success. I borrowed his old broken  driver and delivered a new copy of his driver, as it was before it broke, to him the next day. His old driver shaft  was miss-marked by 1.5 flexes. The odds are that Rex could have tried another hundred drivers with the same lettered flex marked on the shaft band and never found a good match to his old driver. Two weeks later, using my free driver, he won the Lajet Classic and went from 150th to 5th on the PGA Money Winners List that year.  I was able to copy his old club in a few hours using a technique similar to one I was later to patent in 1992 on Golf Club Frequency and Bandwidth Analysis.

Golf club xerography was born .

   In the early 1980’s, knowing that some flexes worked better than others for each player, I tried to come up with a way to find each player’s “best” flex. My training in the early 1970’s in nuclear physics with spectral analysis called gamma ray spectroscopy gave me the idea to build a set of test clubs that would span the entire flex spectrum and identify which flexes worked better than others. Initially, my test club shafts covered the range from Reg to Xstiff  and later included Senior (A flex) and Ladies (L flex) and also the (LL flex), one below Ladies.

.  Each player to be fitted hit shots with each club and the average shot length achieved with each was plotted across the flex spectrum, as shown  on  the Shaft Flex  page, thereby revealing the “best”  flex for that player.  Interestingly enough, players with favorite clubs always tested at the same “best” flex as the favorite, thereby rendering the testing session unnecessary.

   We know that getting just the driver to match the favorite club yields the most benefit compared to other clubs since it is used most  frequently, after the putter. It has been proven just how important increasing fairways hit (FHIR) leads to more greens hit (GHIR) and lower scores. Check those two statistics published after each PGA tournament and compare either to money won.

Find the courage to send your favorite club to me along with your driver, you will be glad you did.
