The eye-level hold is not a prescribed technique for using a compass because it does not effectively allow for accurate readings and can lead to errors in navigation. In contrast, the center hold, compass to cheek method, and wrist method are all established techniques that help in ensuring the compass is used effectively.
The center hold involves keeping the compass directly in front of your body, allowing for a stable and clear view of the compass while aligning it with your point of navigation. The compass to cheek method, which is often used in military and outdoors settings, allows for finer adjustment and a more stable reading by bringing the compass up to your cheekbone, thus allowing for better sighting and confidence in the direction being taken. The wrist method is useful in keeping the compass accessible for quick reference while on the move. These techniques enhance accuracy and safety during navigation, which the eye-level hold fails to achieve.
