When determining the direction of travel using a compass, what must you first identify?

To accurately determine the direction of travel using a compass, it is essential first to identify the declination angle. The declination angle refers to the difference between magnetic north (which your compass points toward) and true north (the actual geographic North Pole). Understanding this angle allows you to make the necessary adjustments to your heading to align your compass reading with true north.

This is crucial because compasses do not always point to true north; they are influenced by the Earth's magnetic field and can vary by location. By accounting for the declination angle, you ensure that your navigation is precise, especially over long distances where small errors can lead to significant deviations from your intended course.

Knowing the declination allows you to correct for navigational discrepancies, helping you reach your intended destination accurately and safely.
