Bushnell Backtrack D-Tour
While "backtrack" and "detour" aren't the most positive words to use when branding a product, the Bushnell Backtrack D-Tour ($100) succeeds anyway. This simple, clip-friendly GPS unit sports a rugged, weather-resistant body, grayscale LCD screen, an internal, rechargeable battery good for 48 hours of data logging, and lets you store up to five locations, with course taken, length in miles and yards, time, latitude, longitude, and other handy metrics to help you recall the exact location of your favorite camping spot, hiking trail, or buried treasure.
