How to Hit High and Low Shots

For the extra technically minded golfers, I used to be hitting a 7-iron and listed here are the launch angle numbers from the video:

With the ball on the regular/heart place, the launch angle was 21 levels;

With the ball ball again in my stance, the launch angle was 18.5 levels; and

With the ball ahead in my stance, the launch angle was 22.5 levels.
