What is the benefit of using the compass to cheek method?

Utilizing the compass to cheek method is particularly advantageous for intersection and resection techniques because it offers a high level of precision in determining one's location or the location of an object. This method involves positioning the compass at cheek level, allowing for both sighting the target and reading the azimuth simultaneously without losing focus on the surrounding terrain. This dual-action is crucial during intersection and resection, where accurate bearings and map interpretation are required to triangulate positions effectively.

In contrast, while the other options mention benefits such as ease of use over rough terrain, navigation in the dark, or swift changes in direction, they do not capture the specific advantages offered by the cheek method for precise mapping and location skills which are essential for intersection and resection techniques.
