When looking for a person or object in the water, a ______ scanning technique should be used.

• A. Random
• B. Focused
• C. Systematic
• D. Circular

Answer: (C)

Systematic scanning means searching the water in an orderly, repeatable pattern so every part of the search area is examined. This approach is essential because it ensures full coverage and helps you keep track of what has been checked, which is crucial in a dynamic water environment where currents and waves can move a person or object. By sweeping the area in fixed lanes or a grid, responders coordinate their positions, avoid gaps, and reduce overlap, increasing the chances of locating the target quickly. Random searching can miss sections, focused scanning may neglect surrounding areas, and circular searching can leave outer zones unchecked—systematic scanning avoids these pitfalls by providing thorough, organized coverage.
