Before Arccos 360 sensors, golfers were in the dark ages when it came to hard data tracking — a terrible fate for those obsessed with the technique-centric game. Now, the Arccos system, which consists of 14 sensors (including one made specifically for putters), attaches to end of the grip on your clubs and pairs with a smartphone app to track performance statistics like distance and accuracy over a span of months. Users can also see course data, such as GPS distances for more than 40,000 courses — all from the screen of a smartphone. It’s the perfect tool for perfectionists and beginners alike.
