Garmin Approach

If your golf game is good enough that knowing the distance between yourself and the hole could mean the difference between bogey and birdie, then perhaps you could use the Garmin Approach ($300). This handheld GPS device comes preloaded with information for over 25,000 courses worldwide, including layup arcs, a 2.6-inch touchscreen for easy zooming and navigation, the ability to keep track of your stats, and an internal rechargeable battery that'll last for a whole weekend of play. Next stop: Q-School.
