4.3.7 Searching
There are three commonly used search patterns. Each suits different conditions. In each case, it is important for searchers to:
- try and observe, or determine from bystanders where the object to be searched for, submerged
- gauge some landmarks which can act as search reference points
- remember that a current may move an object until it comes into contact with the bottom. Once in contact, the object may snag or continue to bump along
- be cognisant that when they surface from searching a sector they should rise vertically, back-peddle a small way then submerge vertically back down. This ensures the searcher doesn’t swim over the object
Zigzag. Used by one or two people in a current. Commencing upstream of where the object had submerged, gradually move downstream zigzagging diagonally across the current using the reference points to ensure the searcher covers the area completely.
Circular. When there is little or no current such as in a dam, commence where it was estimated the object submerged and move around in a circular pattern gradually expanding the circle each time.
