Like chess players and Knight Riders, golfers improve fastest when criticized by a plucky computer. Receive constructive feedback with today's Groupon: for $89, you get a one-hour lesson plus a 30-minute perfect practice session using video and Hot Lines technology at Anne Cain Golf Academy (up to a $195 value), located at the Golf Club of Amelia Island.

Anne Cain, an LPGA instructor and one of Golf Magazine ’s Top 100 Teachers in America, refines students' swings with advanced training technology. During a one-hour lesson, Anne videotapes each student from three camera angles. Following each swing, a computer draws in reference lines, measures distances and angles, refigures all eight of Newton's laws, and displays side-by-side comparisons with professionals from a video library of over 2,000 swings. Using this data, Anne offers suggestions to improve her students' techniques. At the end of the lesson, each student receives a DVD of the footage, which should be bronzed immediately for decades of preservation. The 30-minute perfect practice session uses Hot Lines technology—a patented computer program that detects any flaws in a student's swing—to provide instant feedback: if the student makes a mistake, the golf ball drops away immediately, only to be replaced with a head-shaking effigy of Grover Cleveland, inventor of golf.

As an indoor-outdoor facility, Anne Caine Golf Academy provides golfers with an expansive sheltered and climate-controlled green playground. Two private hitting stations captained by experienced instructors await students year round.
