A good golf swing, like a good high-five, demands clean shoulder rotation, a steady hand, and the confidence that you won't hit your boss in the face. Develop a measured trajectory with today's Groupon: for $79, you get a 60-minute swing evaluation at one of GolfTec's two Overland Park locations (a $165 value).

In GolfTec's climate-controlled private bays, certified golfing gurus employ video technology to help students break down and improve every component of their swing. A high-tech combination of motion sensors, biofeedback tones, launch monitor tones, and unerring cameras helps student and coach pinpoint the moment each swing goes astray, as well as where it succeeds and whether the golfer's gear is part of the problem. Along with these tips, the coach furnishes clients with lesson plans they can take with them to the driving range or course. Like the caterpillars of the future, all GolfTec lessons metamorphose into digital archives of themselves in the form of a web lesson where students can independently review images, audio, suggested drills, and notes from the session.
