Handheld GPS hiking devices, what we tested[SIZE=-1]Magellan Triton 2000 Garmin Oregon 400t * For this report, we bought and tested units of seven different, popular models, listed from lowest priced to highest: Garmin eTrex Venture HC, Magellan Triton 500, Garmin GPSMap 60CSx, Garmin Oregon 200, Magellan Triton 2000, Garmin Colorado 400t, and Garmin Oregon 400t. The new Delorme PN-40 was not available for this test. We focused on mapping units, which can save a detailed trail of where the user has walked. There are less-expensive, non-mapping units, but the loss in functionality is greater than the modest price difference between the types. The tested units ranged from $150 to $640, though lower prices might be available online. All the hiking devices included a base map that indicates major roadways. But no unit could provide turn-by-turn or spoken directions, as is common with portable car navigators. On the other hand, the Garmin Nuvi 500 is a car-type unit similar to the Nuvi 205 in its road performance and features, but it also has hiking features. The Nuvi 500 can serve as a good daily navigator and has the added ability to guide you to a trail, then along it. That would have added appeal for geocachers looking for an all-in-one device. (Complete information is available in our automotive GPS Ratings, which are available to subscribers.) We purchased two units, the Garmin Colorado 400t and Oregon 400t, with topographic maps. All devices in the group can be upgraded with other maps, including "blue" water, city, and topographic choices. But the added cost for such maps can be significant-more than $100 in some cases. With optional city maps, some devices could provide turn-by-turn directions. We did not test that ability. All units provide latitude, longitude, and elevation, and some higher-end models add an electronic compass and altimeter. How we tested To rate the units, our test team performed quantitative evaluations and in-the-field testing. In the lab, we took basic measurements, assessed built-in features, judged ease of use, and measured battery life. For fieldwork, the team hiked many miles with the units and found more than 50 geocaches. We used the units in suburban, urban, and woodland environments. While on the trail, the team observed how each unit performed guidance-related tasks, such as creating waypoints, saving and following user-created trails, panning and zooming maps, being readable in sunlight, and being geocaching friendly. For our guidance score, we considered the following features: electronic compass, three-axis compass, altimeter, topographical maps, map scale, resolution, and the ability to add maps for automotive guidance. While those features can provide useful information, they are targeted at serious outdoor enthusiasts. During our testing, we found that the information from those features was interesting but it was not necessary for basic guidance. In the end, we learned which features matter most and which devices provide the best value for the casual hiker. Posted: December 2008 *[/SIZE] [SIZE=-1]Subscribe now![/SIZE]
