The FitChip gathers club head acceleration/club head speed data which is typically shown in Figure 1. From this data the computer chip analyzes the data to produce the club head acceleration curve as shown in Figure 2. This curve is used to locate the time of peak acceleration (time increment 126) and ball impact (time increment 171). The red line represents the unloading of the shaft, through 1/4 cycle of its natural frequency, from the flexed position, back to straight and square at impact. In this figure two different swings are overlaid to demonstrate the players consistency.

During this time interval, described by the red line, the club releases and must return to straight and square at ball impact for peak performance (best club head speed and accuracy). Matching this timing with the club depends on the natural frequency of the golf club. It is this natural frequency that is derived by the FitChip for each swing. The individual swing frequencies (blue dots) and the average frequencies (red dots) from the FitChip for four different clubs are shown in Figure 3
A line drawn through these points will define the frequencies at which to build a full set of properly fitted clubs, as shown in the following Build-to Table: Figure 4

We build your clubs based upon the slope or curve your Swing Timing requires !
Most standard sets of golf clubs on the market today use identical flex category shafts tipped a consistent increment from club to club, and then butt trimmed to the finished length. This process makes each shaft stiffer by approximately four to five cycles of natural frequency as the clubs get shorter and shorter.
Through thousands of fittings with FitChip, we find that very few players are properly fit with this 4 to 5 degree progression as predetermined by club and shaft manufacturers. Just as a standard size, off the rack suit, not fit properly everywhere on the body, seldom does every club in an off the rack set, fit the players swing timing properly. Most individuals have a unique curve or line depicting their individual swing timing, and their clubs should be built accordingly. Sometimes on straight lines, sometimes on curves, sometimes on positive and sometimes on negative slopes. Everyone is different, and unless you have a set of clubs built with this system, you will never have a fully fitted set of clubs, for which you can say, "every club in my bag is my favorite club."
