In which search technique do searchers need to be highly skilled in navigation and clue detection while roaming within assigned lanes?

The loose grid searching technique requires searchers to be highly skilled in navigation and clue detection while systematically roving within assigned lanes. This method typically involves dividing the search area into a grid pattern and searching it in a thorough, overlapping manner. Searchers must be able to accurately navigate their assigned lanes and identify any clues or evidence of the subject, making their skills in both navigation and clue detection critical elements in the success of this search technique.

In contrast, hasty search primarily focuses on quickly searching a smaller area for signs of a missing person without the same level of systematic navigation. Area searches will cover larger areas, but they are often less methodical in terms of lane assignments. Containment searches focus more on preventing a subject from leaving a certain area rather than the detailed navigation and clue-finding aspects emphasized in loose grid searching.
