Hi Robert. The Equalizer is a software program that was built for standardizing shaft flex for the golf Industry. This system was introduced by the PCS a couple of years back for members only. The package included a shaft with a predetermined frequency( precision shaft with a high swingweight) to use as a calibration shaft that allows 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.In other words if your meter reads 302 with the calibration shaft and mine reads 309 the software will make all necessary adjustments so that we will have the same numbers for a 4.0 slope all the way to a 7.
André.
