Which search pattern is best for a contained or central area?

• A. Grid
• B. Spiral
• C. Quadrant/Zone
• D. Strip/Line

Answer: (B)

When the area is small and contained, you want a search that covers every part of the space without duplication or gaps. A spiral pattern achieves this by letting the searcher move in a continuous, tightening or expanding loop—either starting at the outer edge and moving toward the center or beginning at the center and expanding outward. This approach ensures thorough coverage of the whole area and keeps the search path tight around central features, reducing the chance of missing evidence in the middle. Other patterns are tailored to different conditions: a grid is excellent for larger areas and systematic full coverage in multiple lanes; a strip/line works well for long, open spaces where you can sweep in straight, parallel paths; quadrant/zone patterns divide a larger area into sections for multiple investigators. But for a contained or central area, the spiral pattern provides efficient, complete coverage with a natural, uninterrupted flow.
