Quick Answer
To orientate using a map and compass, you'll need a map, a compass, a straight edge or ruler, and a protractor or angle measurer. A base plate, declination correction tool, and a magnifying glass are also helpful accessories.
Essential Components of a Map and Compass
A map and compass are the foundation of navigation. When choosing a compass, look for one with a clear and sturdy base plate, a reliable dial that rotates smoothly, and a needle that points towards magnetic north. A map should be topographic, with elevation lines and symbols that help you identify terrain features. For orienting, it’s essential to have a straight edge or ruler to draw lines and measure angles.
Key Techniques for Orienting a Map and Compass
To orient a map, align the map’s grid lines with the magnetic north-south direction indicated by your compass. Use the compass’s rotating bezel to align the direction-of-travel arrow with the map’s grid lines. This process ensures that your map and compass are aligned, allowing you to navigate accurately. When measuring angles, use a protractor or angle measurer to determine the direction you need to travel. A declination correction tool is also useful for adjusting for magnetic declination, which can be up to 20 degrees in some areas.
Additional Accessories for Navigation
A base plate with a built-in ruler can be useful for measuring distances and drawing lines. A magnifying glass can help you read small map symbols and markings. For more accurate navigation, consider using a GPS device or a satellite-powered compass. However, these tools are not a replacement for a map and compass, and should be used in conjunction with them to ensure accurate navigation.
