You can view different angles of how you're hitting the ball, as well as the potential distance and trajectory of it, and use that information to see what you can do to improve your stroke. The TruSwing measures a mere 2.40 inches and weighs only 28 grams, making it portable enough for you to take to every golf session -- especially since it hooks onto any club. Garmin says it will sync with some of its Approach watches too, including the S20, a golf-oriented wearable that's being announced today for $200/£180.

As if that wasn't enough, Garmin's also revealing the Approach G10, a tiny clip-on device that will give golfers access to data from over 40,000 golf courses. It'll cost $130/£120, $20/£10 less than the TruSwing, with both expected to ship sometime within the next few months (Q1 2016) -- the same goes for the new Approach S20.
