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

The circular scanning technique is effective for searching for a person or object in the water because it allows for a comprehensive examination of the area. This method enables the searcher to maintain a consistent field of view and cover a larger area systematically. By scanning in a circular pattern, the individual can visually track potential targets and minimize the chances of missing something that may be partially submerged or difficult to see.

This approach also helps manage the dynamics of water movement and can account for changes in visibility due to waves or currents. The circular pattern can be especially useful in situations where the search area is dynamic, as it allows the searcher to adjust their focus and direction continuously while ensuring thorough coverage.
