Why is it important for search and rescue technicians to understand magnetic declination?

Understanding magnetic declination is crucial for search and rescue technicians because it directly affects the accuracy of compass navigation. Magnetic declination is the angle between true north (geographic north) and magnetic north (the direction your compass points). If a technician does not account for this declination, they may misinterpret their direction and make navigation errors, potentially leading them off course.

When searching for missing persons or navigating through challenging terrain, precise navigation is essential for efficiency and safety. By understanding and applying the correct declination value for their area, technicians can ensure that their compass readings reflect true geographic directions, allowing for effective navigation and operation in the field. This foundational knowledge enhances their skills and improves overall mission success during search and rescue operations.
