A golf swing analyzer is any type of feedback that you receive about your golf swing. Now this goes from the basic visual which is normally your golfing buddy watching you and giving you feedback (are they trustworthy?). This particular feedback may not be that helpful but it is basically free. Then on the other side of the scale you have a swing analyzer/golf simulator. This is a very detailed showing of your golf swing and in most instances it is not cheap. Depending on how much time you want to spend and money will be the indicator of which golf swing analyzer you will choose to use.
