The Golf Swing Analyser Watch measures your tempo, rhythm, swing and club speed. It does all this with the help of three – count ‘em – accelerometers and presumably lots of smarts. To be honest if you wanna pay us a paltry sum we’ll save you a lot of grief and tell you exactly what we think of your swing. Of course this may not be quite as helpful, but what the heck…. $399.95.
This device is as unobtrusive as a wristwatch and has three accelerometers (similar to the technology NASA uses to monitor the movements of astronauts in space) that record 200 measurements per second, from the start of the backswing until ball contact, and use s proprietary algorithms to determine if your backswing is a few degrees too long or your tempo if off by as little as 1/100th of a second, allowing you to immediately analyze why a shot went awry or to record the swing measurements that coincided with a shot that split the fairway.
