It is essential to begin your search in the area where the target is most likely to be located.

For example, if you are searching for a knife lost during a dive, start at the last known location along your dive route.

However, if tidal or ocean currents are present, the object may have drifted away from that location.

In such cases, gradually expand the search area in the direction of the current.

Establish search priorities before beginning the operation.
