It is important to start your search in the area where you are most likely to find your target.
For example, if you are searching for the knife that you lost during diving, search your last diving course.

However, if there are tidal currents or ocean currents on the diving course, the object may be moving away from your last diving course.
In such cases, gradually expand the search area based on your last diving course.

Prioritize search areas before starting a search.
