I use it frequently but for my information mostly. Explaining low point or path and face angles can be quite challenging to many students and looking for the difference between a path that is 2 degrees in to out vs. 5 degrees in to out is not helpful to many students. Launch angles for drivers and peak height for some players help then see what proper impact does to the ball. Numbers though tend to confuse them.
