I am fortunate enough to be able to Teach both indoors and outdoors. In season I am outdoors at the course and during the off season, and on inclement weather days, I have a Teaching Studio. In the Teaching Studio I have a GC Quad Launch Monitor, it also is what drives the Simulator.
I taught for years without a Launch Monitor, having a pretty good understanding of ball flight laws makes it fairly easy to “Let the ball tell you what is happening”.
When Teaching Indoors you obviously have to rely on the Launch Monitor, it gives you your simulated ball flight.
What I have found though is using the data really depends on the skill set of the player. Looking at Launch Angles and Spin rates is really proper information for fine tuning a better player. I feel like it is just to much information for a beginner or a high handicap player to digest. With them you are really just looking to build a better swing and working on making better contact.
The Launch Monitor information that has been the most valuable for higher handicaps is the club data. Being able to quantify angle of attack, club path and club face angle at impact has been much more beneficial than analyzing Launch Angles and Spin Rates.
