In the Field
Handheld GPS devices can add enjoyment to a wide range of outdoor activities, and many features cater specifically to hunting, biking, or fishing. Reliable reception is the biggest issue here, however, especially if you’re trekking in cold conditions or under tree cover, and you want a product that is lighter and more rugged than the one you would use in your car. Useful: long battery life, internal memory to store topographical maps and routes, preloaded base maps, SD memory card slot, waterproof up to IPCX-7, and SiRFstar III chipset (provides superior reception). Not useful: large screen (they’re nice, but eat up energy and space), touchscreen (inconvenient for gloved hands), satellite radio or other extras that drain battery life, although digital camera and recording information can be helpful to limit the number of electronics you’re carrying.
Buyer Beware
GPS devices are designed to take some of the thought out of exploring the unknown, but they’re not a license to go on autopilot. Even the best GPS will not save you if you get into terrain or conditions that are beyond your ability, and they’re fallible, just like other machines. But when used in combination with a little common sense, GPS can open up the world.

DeLorme Earthmate
While DeLorme is relatively new to the GPS game, it’s gaining a reputation for smart products and responsive customer service. Its Earthmate PN-20 ($349.95) has gotten a lot of attention for the variety of display options: Users can choose to map their position with aerial photos, satellite images, nautical charts, or National Geographic TOPO! maps, in addition to the standard topographical maps. The Earthmate comes in a durable, rubberized casing, has a bright color screen, and weighs just over 5 ounces. The costs of downloading the fancier maps can add up quickly, and unless you’re a serious enthusiast, you probably won’t need so much power.

Garmin eTrex
For more of an entry-level model, try Garmin’s eTrex handhelds. The eTrex Vista HCx ($321) is at the higher end of the line. Features include a clear, color screen; an electronic compass that works even when you’re standing in place; and a barometric altimeter, so you can keep an eye on changing weather conditions. The stripped-down eTrex Legend ($160) lacks all those frills, and has a 4-scale gray display, but I’ve found it works just fine for basic mapping.
