If you have ever golfed, and are decent, you realize how important real time course information is in order to improve your game. For example, how far is the green from where I am standing, how far is the dogleg, how many strokes have I taken, etc, The Garmin Approach S3 is a golfers best friend, it has a built in GPS, stores course data on over 27,000 courses worldwide, and has a nifty touchscreen interface. Yours for about $350 in black or white.
