Meet the Arccos system: a collection of sensors that attach to your golf clubs to enable you to track your stats in real-time. Arccos captures your data and helps you figure out which areas you need to work on. The Arccos sensor is iPhone friendly. It uses GPS and Bluetooth to map your shots to a bird’s eye view of the course.
The Arccos kit has 14 sensors, one for each club. The companion app has over 18000 courses mapped. The sensors capture your data while Tour Analytics helps you make sense of your data. Not cheap but makes a nice gift for golf lovers.
