Hiking with a global positioning system (GPS) has made orienteering (finding one’s way) a lot easier. When hiking with GPS, it’s always a good idea to have a map on hand in case the GPS loses contact with the satellite that’s feeding it data, the GPS batteries die, or something else unexpected happens. It is critical to become familiar with the GPS and its features before leaving home to go hiking with GPS. Knowing how to use the device before heading out on the trails can save the hiker from a frustrating and potentially dangerous situation.
Before using the GPS on a longer hike, a hiker may want to do some practice runs with it. Hiking with GPS can be extremely beneficial, but only if it is properly configured and the user is familiar with its capabilities. Hikers should begin by using it in their neighborhood or town, and then on short trips into the woods. Once the hiker is comfortable with the unit, he or she can use it as the primary navigation tool on longer hikes. However, having a backup paper map is essential; if the GPS is damaged for any reason, the paper map can still be used to navigate.
When hiking with GPS, keep in mind that any electronic device is only as good as the power source it runs on. Because the device will be useless if the batteries are dead, keep extra batteries in a waterproof container to avoid damage. Some GPS units require special batteries, so before you buy one, make sure you know what kind it uses. To avoid damage that could render the GPS unit inoperable, keep it dry and protected at all times.
The GPS unit may temporarily stop working if a satellite link cannot be established. Make sure the unit is still connected to a satellite and delivering accurate data by checking it frequently. Remember that trails, streets, and other modes of transportation can change over time, so before heading out on a hike with a GPS unit in tow, make sure the maps on the unit are up to date. Most manufacturers provide maps for download from their websites, though some of these downloads may be expensive, so make sure you understand how a GPS unit works before you buy it.
