Apart from golf swing aids which you use on the green, there are other materials which you can use at home. You can buy a golf DVD and then try to practice what you learn by following what the person is saying.
There is also the mirror so you can watch yourself swing. If it is hard to swing and observe yourself in the mirror, get a video recorder and then play it back when you are done.
If you can afford to hire someone as a coach, that will be great because you get feedback from that person instead of second guessing if what you did in the mirror or video is correct.
Golf clinics may be done regularly but how often does it happen where you live? The golf swing aids mentioned can easily be purchased from the sporting goods store. Most of these are sold for under $20 so it will not hurt your pocket so much just to improve your game.
Should the golf swing aids mentioned be not available in the store, check for these items online. It is possible that they are much cheaper here even if you add shipping costs so check what is available.
There are many brands to choose from that sell these various golf swing aids. Before you buy one, check if this is saleable compared to other brands.
If the feedback given by other golf enthusiasts are good, try it out yourself and see if this can improve your game or not. Don’t forget to practice because the golf swing aids can only do so much when what really matters is how well do without them during a game.
