When recording the position of a clue to take back to Incident Base, what should you also do?

Marking the position of the clue is crucial because it ensures that the exact location can be easily identified and revisited by other team members. This detailed marking allows for accurate reporting and documentation of the clue's location, which is vital for further investigations and searches.

Additionally, marking helps to maintain the integrity of the evidence and provides a point of reference for search and rescue personnel. A well-marked position minimizes the risk of losing track of key evidence and ensures that the team can systematically search or return to the area.

The other options do not directly contribute to the effectiveness of preserving the evidence or maintaining operational efficiency during search and rescue efforts.
