To Cut Your Golf Handicap, Get Wired

A golf pro can help you perfect that power swing or kill off a nasty slice. But "a golf lesson has the lasting value of a couple of drinks," says PGA pro Michael McTeigue. McTeigue, who is also president of SportSense Inc., thinks he can make the training stick with a four-part electronic system that corrects a golfer's stance and swing.

The Golf Swing Tuner (GST) uses a sensor worn inside the shoe to measure the weight transfer from one foot to the other as you swing. Another, attached to your club, tallies the tightness of your grip. Sensors strapped to your back measure how quickly your body twists and calculate the angle of your shoulders and waist during the swing. Finally, sensors in your cap warn if you bounce up and down or lean too much. The modules, about $100 each, send signals to a $250 Walkman-size computer that tallies the results and beeps you through headphones to signal whether you are in or out of proper form. The first two units are on the market. The Mountain View (Calif.) company will release the last two in 1993.
