This swing analyzer has one big advantage over competing products like the older SensoGlove: It attaches to any existing golf glove. Using Bluetooth to sync the data, your phone (iOS or Android) or tablet (iPad only) can shows exact swing arc, speed, and angle. Training aids go beyond the norm: You can get tips on wrist position, swing plane, and tempo. Once you have finished a training session, save the results to the cloud for closer inspection off the course. [$130;]
