Search
Further information: Underwater searchesUnderwater searches, much like above water searches, are designed around specific search patterns. The most common forms of underwater search patterns are:
- Circular search
- Jackstay search
- Expanding square search
- "U" pattern search
The patterns are usually performed by divers in pairs or teams below the water, but they can also be conducted by use of a tender who may be a snorkeller at the surface, a person on a towing boat, or a person located on the shore.
In simple search operations, the patterns will usually be conducted by the divers simply looking visually for the object. In more sophisticated search operations, underwater magnetometers or hand held sonar may be used.

Famous quotes containing the word search:
“On short, still days
At the shut of the year
We search the pathways
Where the coverts were.”
—Philip Larkin (1922–1986)

—Eric Hoffer (1902–1983)
“I never found even in my juvenile hours that it was necessary to go a thousand miles in search of themes for moralizing.”
—Horace Walpole (1717–1797)
