What is the best method for searching a large area?

• A. Line-by-line inspection
• B. Crawl-through method
• C. Spot-checks only
• D. Strip & grid

Answer: (D)

When searching a large outdoor area, you need a system that guarantees every patch of ground is covered without leaving big gaps. The strip-and-grid approach does this by organizing movement into long, straight lanes (strips) that teams sweep in one direction, then adding a second set of passes perpendicular to those lanes to form a grid. This creates overlapping coverage, so it's unlikely any area is missed and you have a clear record of what has been covered. It scales well to large spaces, makes efficient use of multiple teams, and helps you track progress and boundaries, reducing duplication and missed zones. Other methods tend to fall short in large areas. Line-by-line inspection can be slow and easy to miss ground between lines. A crawl-through is impractical for expansive terrain. Spot-checks leave large portions unchecked and rely on luck rather than dependable coverage. The strip-and-grid method intentionally covers ground in a controlled, verifiable way, which is why it’s the best choice for large-area searches.
