This system was introduced by the PCS a couple of years back for members only. The package included a shaft with a predetermined frequency to use a s a calibration shaft that will allow you to make a correction change in the software, so that you and I can build clubs that will be the same flex on either of our frequency analyzers. The software has undergone a major upgrade and will be unveiled at the PGA Show in Orlando. It is my understanding that the Equalizer Flex System will be made available to all interested clubmakers, not just PCS members. This system maybe the industry standard down the road, it is worth looking into.
