Which methods are used for holding a compass?

Explanation:
Holding the compass with a stable, repeatable setup is the key to getting accurate bearings. The two commonly taught methods—pressing the compass against your cheek and using a center hold—provide that stability and keep your line of sight aligned with the instrument. In the compass to cheek method, you bring the compass up to your cheek so your eye is at a fixed distance from the sighting line. This closeness helps minimize parallax and ensures you read the bearing consistently through the sighting window. It’s especially useful when you’re lining up a bearing along a distant landmark and need steady, repeatable sighting. The center hold technique places the compass in the center of your palm, with your fingers supporting it so the case stays level. This grip minimizes hand shake and keeps the bezel turning smoothly without altering your eye position, which helps when you read or recheck bearings. These methods are favored because they lessen movement and parallax errors, giving you reliable readings in the field. The other options describe grips or positions that aren’t standard or practical for compass use and don’t offer the same stability for accurate bearing readings.
