Geocaching
Garmin Colorado 400t
Weight: 7.3 ounces (with batteries)
Screen: High-resolution color
Battery life: 15 hours
Price:$639.99
Link: Garmin Colorado 400t
Geocaching is a sport made for GPS. A sort of high-tech treasure hunt, the idea of geocaching is for players to set up caches anywhere and everywhere in the physical world. Players publish the locations of these caches on the Internet, and others navigate to the caches using GPS units. A cache can contain tokens or items of value as a reward. Coordinates can be found on geocaching.com.
It's a fun way to get exercise and a great way to get tech-savvy kids away from their video games and out for a hike. The Garmin Colorado 400t, with built-in topographical maps of the U.S., is the perfect electronic companion for the hunt. The Colorado displays the full geocache description, cache size, difficulty / terrain ratings, and recent logs. One caveat here -- high resolution screens, while they present a gorgeous display, tend to be less bright than those found on other GPS units. Read a review of the Colorado here.
Now that you're used to relying on a GPS receiver to guide you across highways and through traffic, how will you get around when you arrive at your destination?
If you're walking around a metropolitan area, Google's walking directions can help you. But If your destination is the great outdoors, chances are there's a handheld GPS unit for whatever activity you've got planned.
GPS receivers are becoming more specialized than ever, and nowhere is this truer than in the sport and handheld category, where there are units designed for runners, cyclists, golfers, hunters, fishing and boating enthusiasts, and more. We'll investigate eight highly specialized devices before looking at five others that will meet a wider range of outdoor needs.
A word about maps: Detailed maps can be added to most of the GPS receivers covered in this article. Unlike auto units though, most handhelds don't come with pre-loaded maps; in most cases you'll have to pay extra for them.
