Unfortunately, there are a variety of errors that can lead to hitting a thin shot, so you are going to have to work through your own swing carefully to find the true cause of the problem. It is impossible to fix a problem until you first identify it accurately, so that is your job at the start. Once you are clear as to why you are hitting too many thin shots, you can then go about the business of fixing the mistake.

One of the most important skills you can possess as a golfer is the ability to hit the ball the right distance time after time. Hitting shots off line is part of the game, but if you can improve the control you have over the distance of your shots, you will instantly become a better player. To do that, you need to find the sweet spot as often as possible. Thin shots will actually fly on line quite frequently, but they will rarely travel the right distance. Prioritize the ability to make contact on the sweet spot and you will find that the game becomes much easier.
