What does a spiral search pattern primarily utilize?

A spiral search pattern primarily utilizes a series of concentric circles to systematically cover an area. This search technique is particularly effective in scenarios where the searcher starts from a central point and works outward or inward, ensuring that all areas are examined thoroughly without missing any spots. The concentric circles allow the searcher to maintain a consistent distance from the center, which aids in an organized and methodical approach to searching.

In situations such as crime scene investigations, the spiral pattern helps in concentrating the search effort where evidence is most likely to be found, particularly if a person or item moved away from a specific point. This method is favored for its efficiency in visually covering the entire area while minimizing the chances of overlooking important evidence.
