Quick Answer
A GPS backup is highly recommended when using paper maps, as it can ensure navigation in situations where maps are water-damaged, lost, or obscured by environmental factors.
Importance of Backup Navigation Systems
When venturing into the wilderness or unfamiliar territories, relying solely on paper maps can be a significant risk. Weather conditions, such as heavy rain or snow, can render paper maps useless. Moreover, physical damage or loss of the map can be catastrophic in a survival situation. A GPS device can provide crucial navigation assistance, but it’s also susceptible to failure due to battery drain or physical damage.
Choosing a Reliable GPS Backup
A good GPS backup should be compact, lightweight, and have a reliable power source. Consider using a hand-crank or solar-powered GPS device, such as the Garmin inReach or the Brunton Terra GPS. These devices can provide essential navigation data, including coordinates, altitude, and even satellite imaging, which can aid in route-finding and terrain awareness. Make sure to test your GPS backup regularly to ensure its functionality and accuracy.
Integrating Paper Maps and GPS Backups
To maximize navigation efficiency, combine paper maps with GPS backups. Before your journey, study your maps to understand the terrain, landmarks, and potential hazards. Then, use your GPS device to track your route and mark notable features on your map. This approach will enable you to create a hybrid navigation system that leverages the strengths of both paper maps and GPS devices. Always remember to carry extra batteries, a map case, and a repair kit for your GPS device to ensure a reliable backup.
