I have just watched a series of video's on YouTube by Mark Crossfield which highlighted the benefits of using devices such as Game Golf.
If you have never used Game Golf and don't know what it is, let me explain.
In the Game Golf package you receive a clip for your belt and 14 tags which you put into the end of each club in your bag. Before each shot you "tag" your shot by clicking your tag onto the belt clip.
This clip measures where you are via GPS and tracks your stats during a round of golf. At the end of the round you download the data onto your computer and it produces stats from your round.
I use Game Golf with several of my students and I find it a big help. It allows me to analyse a students game using facts plus it allows me to see exactly what the tendencies are when I'm not with them.
IT ALSO HELPS ME AND MY STUDENTS MEASURE THEIR GAME AFTER THE LESSON TO SEE IF WHAT WE HAVE WORKED ON HAS WORKED
In Mark Crossfield's video's he shows how he analysed a players stats such as greens in regulation. He then noted that the player had a tendency to miss short of the green and therefore could work on the players technique based on these facts.
