Quick Answer
When choosing navigation tools, consider your environment, time constraints, and personal skills to select the most effective tools. A compass, map, and GPS are essential for navigation, but it's crucial to understand their limitations and how to use them in conjunction. Familiarize yourself with these tools before an emergency.
Choosing the Right Compass
In a whiteout situation, a magnetic compass is essential for navigation. Look for a compass with a clear and readable face, preferably with a rotating bezel for easy referencing. A compass with a declination adjustment is also necessary for accurate readings. Familiarize yourself with how to use a compass in conjunction with a map to plot a course. Practice using a compass in different environments and conditions to develop your skills.
Reading the Map
A map is a critical navigation tool, and it’s essential to understand how to read it accurately. Use the map to identify landmarks, topography, and water sources. When navigating in a whiteout situation, use the map to identify the direction of the sun or the position of the North Star. Make sure to use a scale ruler or a measuring device to measure distances on the map. Practice using a map in conjunction with a compass to identify your location and plot a course.
Using a GPS Device
A GPS device can be a lifesaver in a whiteout situation, but it’s essential to understand how to use it effectively. Look for a GPS device with a long battery life, a clear display, and accurate satellite reception. Practice using the GPS device in different environments and conditions to develop your skills. Learn how to use the GPS device in conjunction with a map and compass to identify your location and plot a course. Consider using a handheld GPS device or a smartphone app with a GPS function.
