Which method is NOT a common way to hold a compass?

The circle-hold method is not a recognized or standard way to hold a compass in navigation. The center-hold method involves holding the compass flat in the palm of your hand, allowing for a clear view of the needle while maintaining stability. The compass to cheek method utilizes the cheek as a point of reference, enabling the user to align the compass with their line of sight and keep the compass level. The eye-level method involves raising the compass to eye level, which allows for precise reading and alignment with distant landmarks.

In contrast, the circle-hold method does not have established techniques or usage in compass navigation, which is why it is categorized as incorrect in this context. Understanding these methods is crucial for effective navigation, allowing users to accurately determine their heading and maintain orientation in the field.
