In concentric circle search, what pattern is recommended?

• A. Clockwise.
• B. Counterclockwise.
• C. Spiral outward only.
• D. Random path.

Answer: (A)

Concentric circle search is about systematically covering an area by moving in expanding rings around a central point. You sweep each ring in a consistent direction so every sector is checked in a predictable order, then step outward to the next radius and repeat. Sweeping clockwise around each circle provides a steady, repeatable pattern that teams can rehearse, making coordination easier and reducing the chance of gaps as the search radius grows. It also aligns with common navigation conventions where bearings and calls are typically processed in a clockwise sense, helping maintain clear situational awareness. While a counterclockwise sweep is the same concept in the mirror, sticking to a single, standard direction avoids confusion. A spiral outward path or a random path abandons the structured coverage that concentric rings are designed to enforce and tends to produce inefficiencies or missed areas.
