The Golf Swing Analyzing Watch

Used by professional golfers, this watch identifies imperfections in your golf swing and helps you improve your stroke. The watch measures tempo, rhythm, backswing length, and club-head speed and instantly displays metrics for each on the watchface. After hitting a good shot, you can use the measurements as benchmarks for consistent, optimal ball-striking and to quantify the elusive "perfect swing." Three accelerometers (similar to the technology NASA uses to monitor the movements of astronauts in space) record 200 measurements per second--from the start of the backswing until ball contact--and use proprietary algorithms to determine if your backswing is a few degrees too long or your tempo is off by as little as 1/100th of a second. The watch records swing measurements for each club in your bag, it has four scorekeeping modes, retains handicaps for two golfers, and records separate statistics for tee-shots, fairway-shots, and putts. The watch has clock, calendar, alarm, and stopwatch functions. Water resistant down to 100'. Battery included.
