Mastering Compass Bearings: Navigate with Precision
Introduction
In the realm of navigation, the compass bearing reigns supreme, providing intrepid explorers and seasoned travelers alike with an indispensable tool for determining direction and charting a course. Whether embarking on a rugged wilderness expedition or simply navigating urban landscapes, an understanding of compass bearings is essential for accurate and efficient travel.
Basic Concepts
At its core, a compass bearing is a measurement of the angle between the magnetic north pole and the direction of travel. It is expressed in degrees, ranging from 0° to 360°, with north being 0°. To determine the compass bearing to a target, align the compass's magnetic needle with magnetic north, then read the angle indicated on the compass dial that corresponds to the direction of travel.

| Magnetic North |
The reference point for all compass bearings |
| True North |
The Earth's geographical north pole |
| Declination |
The angle between magnetic north and true north |
| Variation |
The local deviation between magnetic north and true north |
Getting Started
Mastering compass bearings requires a combination of understanding and practice. Begin by ensuring your compass is properly calibrated and adjusted for the local area. Familiarize yourself with the compass dial and learn to align the needle with magnetic north accurately.

Instructions |
|
1. Set the Declination: Adjust the compass for local declination. |
|
|
2. Align the Needle: Rotate the compass until the red end of the needle points to magnetic north. |
|
|
3. Read the Bearing: Note the angle on the dial that corresponds to the direction of travel. |
|
|
4. Use the Bearing: Transfer the bearing to a map or use it to guide your path. |
