Golf O Max allows you to play golf indoors all year round at over 50 world class courses. Their full swing simulators have mats that simulate fairway, rough and sand. The simulator screen is 10ftx12ft and the system uses dual infrared tracking with 688 independent sensors 1 1/2 inches apart to provide real time display based on your actual swing. You can hit on the driving range or practice your chipping and putting with different irons. The simulators provide statistics on your shots such as: carry distance, launch angle, ball speed, distance to pin and deviation off the target line.
