Which characteristic describes an expanding square search pattern?

An expanding square search pattern is particularly effective for searching an area where a diver believes an object or person might be located. This pattern involves starting from a central point and systematically radiating outward in a square-shaped grid. The technique allows divers to progressively cover more area while effectively searching the vicinity without leaving gaps.

The method is specifically designed for scenarios where the searchable area is likely limited, making it perfectly suited for looking for something lost in the immediate area. As the pattern expands outward, it provides the ability to systematically explore the space and ensures that the area is covered efficiently.

In contrast, other patterns or methods may be better suited for larger or more open areas (which is not the defining feature of an expanding square pattern) and typically don't require specialized gear, as the basic diving equipment suffices. Also, the expanding square pattern can be effectively executed by larger teams, making the claim of being limited to small teams inaccurate.
