Watches that use GPS to help you on the course are nothing new. Clip-on swing trackers are old news. But a wearable that combines them both? Now you've got something. The Garmin Approach S6 GPS Golf Watch continues the GPS-maker's golfing line with a host of sensors that it uses to track your swing tempo and speed, comparing your tempo against the ideal ratio and giving you audible tones to improve your mechanics. Of course, it's also got serious GPS chops, with detailed, full-color views of over 30,000 courses, the Pin Pointer to help with blind shots to the green, a green view that allows you to move the pin to its current location, and the ability to keep your score and measure your distance on big shots.
