another feature, press and release MODE until the appropriate
mode is displayed .
Critical to accurate club recommendations is the known striking
distance of the user with specific clubs . By inputting the actual
distance obtained with a few clubs, a specialized algorithm
accurately determines the distance obtained with others .
The actual distance obtained from an 8-iron, 6-iron, and 4-iron
shot should be input as accurately as possible .
If no club distance is input, the Club Selector will automatically
default to the preset distances (130 yards for an 8-iron, 150
yards for a 6-iron, and 170 yards for a 4-iron) . In addition to the
striking distances, the temperature and altitude at which these
distances were measured must be input following the distance
input process . By entering the environmental conditions in
which the specific distances were obtained, the Club Selector
will be able to adjust the recommended iron according to the
current conditions .
NOTE: Though we strongly recommend inputting the specific
distances obtained with each of the irons mentioned above,
the specialized algorithms used by the GX-5c will make logical
assumptions about the remaining club(s) if specific distances are
not known for one or more of the remaining clubs.
