Hitting the ball straight is every golfer's dream. The revolutionary patent pending SDF is an effective golf training aid that will make your dream of great golfing come true. It doesn't matter if you are left handed or right handed, an experienced or beginning golfer. The SDF works for everyone. You can train with the SDF at the driving range or you can even train with the SDF inside when the weather doesn't permit you to go out. The SDF can be used with any club. They recommend that you use the driver.

We enjoyed working with the SDF because it is really easy to use. Sometimes the best training aids are the simplest ones. Having the SDF on your driver gives you extended reference lines to show you proper positioning at various points in the swing. With out the device on the club it is very difficult to see what is square and what is parallel to the target line. Like any other training it's effectiveness is a function of how much time you spend with it and how dedicated you are to improving your game.
