A golf swing analyzer is an electronic device, which is especially designed to lend a helping hand to golfers seeking to improve the mechanics of their game. A golf swing analyzer is particularly suitable for those who want to improve their game without spending hours on a golf course. This device can point out one's swing errors and provide feedback in an indoor setting.

Basically, a golf swing analyzer can be one of two types: simple home devices and more sophisticated systems found at golf centers. The prices of a golf swing analyzer can vary greatly depending on its quality. For example, while a basic mechanism can cost just a hundred dollars, a golf center package offering a computer generated analysis and instruction can leave one poorer by several thousand dollars. You can purchase the simple, home golf swing analyzer from golf pro shops, specialty sports stores, and on the Internet.

In the most basic golf swing analyzer, a small electronic contraption can be attached to a club shaft. As the golfer swings the club, the golf swing analyzer records his/her club speed and computes a distance projection.

A home golf swing analyzer can be available with sophisticated computer software packages. Basically, they work in the following fashion: the golfer records his/her swing on a video or digital camera; this swing information on the camera is downloaded into a computer program; special computer software analyzes the club head speed, the club head path and the club face angle; the computer predicts the distance and trajectory of the ball; and, a computer program recommends swing improvements. Some computer programs also provide a side-by-side comparison of the recorded swing to that of an "ideal swing."

The most sophisticated and expensive analysis systems are to be found at golf centers. To begin analysis session, a golfer addresses a golf ball at a tee box (usually indoors). Usually, the tee box has synthetic turf and a net to capture the golf balls after they have been hit. The golfer hits a series of golf shots into the net for a professional cameraman to record the swing.

Similar to that in the home version, the swing is transformed into a computer image for assessment. The software program analyzes the biomechanics of the player's swing. Apart from the standard swing information, a sophisticated golf analysis system provides feedback on body alignment, stance, hand position, and head movement.

When buying a golf swing analysis package, the golfer often receives a video or CD to take home as well as computer printouts. Many golf centers provide instruction on improving any swing errors identified in the analysis.

When used thoughtfully, a golf swing analyzer can help a golfer hit the ball further with greater accuracy and greater consistency.
