Garmin Approach S3
We've seen several GPS-enabled golfing assistants, but the trouble with those is often simply remembering to bring them along. The Garmin Approach S3 ($350) alleviates this problem by taking the form of a touchscreen GPS watch, giving you handy access to data for over 27,000 courses worldwide — including distances to doglegs, layup points, and pins — a rugged, waterproof body, and a "digital caddy" to keep track of your strokes.
