If a guide is instructed to maintain a bearing of 15 degrees, what role does the compass play in this instruction?

The compass plays a crucial role in maintaining a bearing of 15 degrees by providing a precise means to determine and follow the desired travel direction. A bearing on a compass is a way of indicating direction in degrees, measured from true north. When a guide is instructed to maintain a specific bearing, such as 15 degrees, the compass helps them align their path with that bearing.

Using the compass, the guide can continuously check their orientation against the fixed direction in which they need to travel, ensuring they stay on track. This is particularly important in navigation where visual landmarks may be absent or difficult to identify, and a consistent direction must be maintained over potentially long distances. Other options, like indicating terrain features, showing speed of movement, or contacting base, do not directly relate to the primary function of maintaining a specific travel direction, which is essential for navigation and safety in search and rescue operations.
