Quick Answer
To use a compass effectively in emergency situations, hold it level, stabilize your hand, and align the direction-of-travel arrow with the magnetic needle. Use the orienting arrow and a landmark to set your bearing, then start walking. This process should be repeated at regular intervals to stay on course.
Understanding Your Compass
A basic compass consists of a magnetic needle, an orienting arrow, a direction-of-travel arrow, and a rotating bezel with degree markings. The magnetic needle points towards the Earth’s magnetic north pole, while the orienting arrow is aligned with the magnetic needle when the compass is level. The direction-of-travel arrow shows the direction you need to go.
Setting Your Bearing
To set your bearing, first locate a landmark such as a mountain or a river. Next, align the direction-of-travel arrow with the landmark and the orienting arrow. Use the rotating bezel to rotate the compass dial until the direction-of-travel arrow points towards the landmark. Take note of the degree reading on the bezel, which will be your bearing.
Maintaining Your Course
To maintain your course, use the compass to check your bearing at regular intervals, such as every 30 minutes. Take note of any changes in your surroundings or the position of landmarks, and adjust your course accordingly. If you notice that you are deviating from your course, use the compass to set a new bearing and continue walking. When traveling in a group, it’s essential to communicate your bearing and course changes to ensure everyone stays on track.
