What is the main purpose of the orienteering lines on a compass?

The main purpose of the orienteering lines on a compass is to assist in determining a bearing to an object when used in conjunction with a map. These lines, often referred to as sighting lines or direction of travel arrows, help the user align the compass with a specific point on the map to establish the direction they need to travel. By allowing for precise alignment with topographical features shown on a map, orienteering lines facilitate accurate navigation, enabling hunters and outdoor enthusiasts to find their way effectively in the wilderness. This process ensures that they are traveling in the right direction to reach their desired destination or to identify their current location relative to known map features.
