The Optishot Infrared (IR) Golf Simulator costs only $400 and can fit in a laptop bag, whereas most other simulators require a room, projector, hitting net and about $14K in cash. With the base system you receive the IR sensor pad and software for your computer. The sensor pad reads your clubface angle at impact (how many degrees open or closed the face is), path and clubhead speed, then projects a fairly accurate ball flight on a screen which duplicates such famous golf courses as Bethpage Black and Torrey Pines.
The simulator comes with foam golf balls which you can hit safely into a curtain or wall at home – just make sure you have at least 8-1/2 feet of clearance and plenty of room to swing. Dancin' Dogg is also currently working on an online system that will allow you to play with or against other people.
