What To Look For
Most backpackers will say the most valuable tools in their packs are topo maps and compass. But the multi-function GPS unit is quickly taking the place of these. If you're in the market for a GPS unit, look for one that has a long-life battery, 12 channels for a greater chance of picking up a signal in a sheltered area and a minimum of 20 megs of memory for additional maps. It should also be waterproof and lightweight.
Common Pitfalls
Skimping on cost often means skimping on features. While you might not need everything available on deluxe models, it's a good idea to do an inventory of your backpacking style and needs before buying and go for the best model you can afford. Don't try to use you car GPS for backpacking either; most are not equipped with what you need for backpacking
Where To Buy
Sporting goods stores are beginning to stock more hand-held GPS units that are suitable for backpacking. Big-box stores usually carry a large selection, and if you live in an area where there is a lot of hiking, smaller stores will often stock GPS units with features needed for that area. Amazon also carries an extensive selection as well as specialty sites such as Campmor and REI.
Cost
Because backpacking GPS units are smaller and more rugged than most car units, they tend to be pricier. Tricked-out units that have large memories and plenty of features will run more than $500 as of September 2009. On the other end of the spectrum, there are models that are less than $100 but do little more than get you back to your starting point. Most models fall in the $200 to $300 range and will offer flexible features and upgrades.
Comparison Shopping
Garmin's Colorado 400t has a handy scroll wheel for one-handed navigating and a data storage unit that is rated as excellent, but it is a little pricey at around $450. Bushnell's Back Track is a stripped-down model that will get you back to the trail head for $65. And Magellan makes a line of hand-helds for around $150. Garmin has several highly rated models from $160 to $190, and the e-Trex H can be found for less than $100.
Accessories
A car charger is essential to be fully charged when starting the hike. If you are going on a long trip that exceeds the reasonable life of the battery, investing in a backup battery will be worth it. Additional topo maps for the area are other accessories you can't do without.
Insider Tips
Despite booster systems and multiple channels, it still might be difficult to get a signal under dense canopy. If you are hiking in areas with heavy cover, bring backup maps just in case.
