Trace Action Sport Monitor
If you've always wanted a way to track, measure, and share everything you do on your skateboard, surfboard, or snowboard, look no further than the Trace Action Sport Monitor ($150). It uses a combination of GPS and inertial sensors to record tricks, map out runs, and provide tons of useful data that you can share with the included sport-specific apps for iOS or Android. This hockey-puck-like device is about the size of a peanut butter cup, and attaches to your board of choice with a rugged mount — it's also durable and waterproof, so it will stand up just about anything.
