What should a searcher's approach be when faced with challenging terrain like undergrowth?

When approaching challenging terrain such as undergrowth, it is crucial for a searcher to adjust their search strategy according to visibility. This is necessary because visibility can significantly impact the effectiveness of the search operation. In dense undergrowth, sight may be severely limited, making it more difficult to locate individuals or clues. As a result, searchers must adapt their techniques; they might need to use alternative methods, such as sound cues, tracking, or utilizing tools to enhance visibility.

Adapting the search strategy allows the team to cover the area more effectively, ensuring that they are using the best available resources and strategies to compensate for the challenges posed by the terrain. This strategic adjustment may also involve changing the spacing between searchers, altering the search pattern, or using different types of search techniques that are better suited for low-visibility environments.

Considering visibility and altering the approach is essential to ensure a thorough and efficient search, ultimately increasing the chances of a successful outcome.
