I've had this for a couple weeks now and have played a few rounds on TGC. Pretty fun. As others have noted, this won't register fat and thin swings. My distances also seemed off (short 15 to 20). Adjustments to the club's loft and shaft length (from head to bottom of sensor) helped dial my real distances I guess by changing club speed. It seems like path and club angle at impact are accurate. Can't really tell on side spin and have toed some swings that register as straight shots.
At the midpoint price level is Golfzon’s Vision Standard. Don’t let the name fool you—it’s far from a Spartan offering. The system’s sensors capture your swing, impact and spin, not only displaying your ball flight but recording key data points, which are stored via the cloud on various electronic devices. With 180 elegant courses and dozens of practice arcade games, boredom will not be an issue.
