Arccos Golf Tracking System
Never mind trying to fix your swing — the Arccos Golf Tracking System will try to make the most of your game using the swing you have. It does so with an army of 14 sensors that attach to each of your clubs and talk to the companion app while you play. Using GPS info from your phone, it knows how far you're hitting each club, as well as how far you are from the green, and can use that to make in-round club recommendations (right on your wrist if you're wearing an Apple Watch). It only gets smarter over time, logs each of your rounds, and since the sensors attach to the hole in the grip end your club, they can be easily transferred when you buy a new set.
