You don't want to be the jerk on the golf course who's constantly glued to his phone — no one likes that guy. With the Garmin Approach S4 GPS Golf Watch ($350), you won't have to be. Just like the previous versions, this GPS watch comes loaded with a database of more than 30,000 golf courses that you can access on the the built-in touchscreen display. Unlike previous versions, it comes with Bluetooth connectivity, letting you discreetly view notifications about calls, emails, and texts without taking your phone out of your pocket. Additionally, it lets you monitor analytics about your golf game, so you can gradually improve using real-life data that's unique to you.
