Does
Club Fitting by Computer Work? It Depends.
In recent years
with the introduction of electronic devises that measure frequency,
acceleration pattern, swing path, swing speed and launch angle,
the process of club fitting has taken on a technical edge. A number
of club makers have taken it up themselves to develop a fitting
program that is based solely on fitting parameters covered by these
new instruments.
Fitting is a
dynamic process that requires an experienced club fitter to observe
upward of 23 parameters and then to recommend an optimal solution
to the golfer seeking help. A successful fitting process should
combine information provided by electronic instruments with careful
observation of a golfer's swing and swing variations to reach a
final recommendation.
The following
is a list of club fitting parameters. We divide the list into three
groups: Golfer, Shaft and Club Head to reflect the particular parameter's
origin.

We
recommend club makers to take full advantage of what technology
has to offer. Unfortunately, no electronic devise available today
measures all 23 parameters. Any fitting process that does not taken
into consideration all relevant parameters is naturally unreliable.
Just ask yourself which one of the above parameters you can ignore
and still find the optimal club and shaft combination. This is partially
the reason why Harrison no longer publishes a fitting chart, because
no matter how well constructed the chart is. It can only fitting
a very limited number of golfers.
The
following is an incomplete list of available fitting instruments
and what they measure.

Every
one of these devises provides information on only a handful of parameters.
A fitting process that predicates solely on one or even two of the
devises listed above while ignoring the rest of the parameters will
only have a random chance of success. A successful club fitter is
one who uses information, collected through observation, research
and electronic means, on all fitting parameters in making his final
recommendation.
