Storing Shot Data in the PureFlight
™
The PureFlight™ is a microprocessor based unit with an internal memory that can store
up to 1000 shots, saved in up to 99 sessions. Examples of how a session or set of
sessions can be defined include the following:
• Golfer A hits 10 shots each with 8 different clubs for averages by club on a given
day and saves as Session 1. Then Golfer A hits 10 shots with each of the same
clubs three months later and saves as Session 8 (for example). Golfer A then
compares the two sets of averages to determine any changes in their game.
• Golfer B hits six shots with Driver X in Session 1, then hits six shots with Driver
Y and saves in Session 2 and compares the two sets of averages to judge
comparative performance.
• Golfer C hits six shots with each of their clubs in a single session, uploads the
data to the PureFlight™ Practice program, and prints out average distance by club
on a “bag tag” to carry with them on the course.
