Golf simulators allow you to do all kind of golfing activities. Different simulators offer different things, so be sure and find out what you want before buying one.
The main thing that a golf simulator does is allow you to play different computerized golf courses. Most programs will allow you to pick from all kinds of gorgeous facilities, including Augusta and Pebble Beach. You can either play alone or with some friends. Rounds usually take about an hour if you play by yourself, and longer depending on how many people are with you. With most programs, you don't have to keep track of your own score, because the computer keeps track of your strokes for you. Before you start playing, you can enter in player's names, handicaps, and whether they are right or left handed. Then once you are done with your round, it calculates the score and tells you the winner.
If you are not in the mood to play a full round, or if you are in the middle of a golf lesson, the driving range feature might be the best option for you. On this driving range, you can do anything that you would do on a normal driving range. Pick your club, and aim at different targets all over the range. This is a great thing for players who do not know how far they hit each club. Using this simulator can greatly help accuracy and distance.
Other programs even offer a par three shootout. This allows you to play 18 holes of par three's. This is a great way to practice hitting greens in regulation and a great way to start golf for new golfers.
Most simulators are video and DVD compatible. So, whenever you are not hitting golf balls, the screen doubles as a great home theater. It can also be hooked up to some golf video games so you can be the player in the video game.
