Quick Answer
When a map and compass are preferable to electronic navigation is in wilderness or remote areas where devices are unreliable due to low signal or dead batteries, and a paper map can be used to guide you even without a compass.
Electronic Navigation Limitations
In areas with dense foliage, caves, or steep terrain, electronic signals may not penetrate well, rendering GPS devices unreliable. For example, GPS signals may be blocked by mountains with an elevation of 2,000 feet or more. In these situations, a map and compass can provide a more reliable navigation tool.
Manual Navigation Techniques
Using a map and compass in conjunction with natural navigation techniques, such as reading the sun and using landmarks, can provide a reliable means of navigation. To use a compass, orient the map with the compass needle, and then use the compass to guide you along the desired route. It’s also essential to understand the principles of triangulation and how to use it to navigate long distances. For instance, if you’re heading east and need to travel 10 miles, you can use the position of the sun to estimate your direction and then use the map to guide you.
Preparing for Wilderness Navigation
Before venturing into the wilderness, it’s essential to prepare by learning basic navigation skills, such as using a map and compass. Practice using a map and compass in different conditions to build your skills and confidence. Additionally, always carry a spare battery for your GPS device and a paper map, as well as a compass, in case your electronic devices fail.
