I have learned a great deal using TrackMan with my students. It is especially useful for seeing angle of attack. I’ve given 40,000 lessons. I can generally see club path and club face but angle of attack in my opinion is impossible to determine without TrackMan. Divots mean nothing. Many low handicap players hit hooks because of a positive an angle of attack or hit fades because of negative angle of attack. I found it is easy to misidentify swing flaws without a great launch monitor and an understanding of the data it provides you.
