How it Works:
1. Alignment: The compass needle aligns itself with the Earth's magnetic field.
2. Sighting: You use the sighting mirror to align the compass with your desired direction.
3. Reading: The magnified compass card and needle are clearly visible through the lens, making it easier to read the bearing.
Advantages:
