Methods of Conducting a Search
- Strip Method
- Double Strip or Grid Method
- Spiral Method
- Wheel/ Ray Method

Strip Method
The searcher proceeds slowly at the same pace along the path parallel to one side of the rectangle.
Strip Method
This search is a modification of the strip search method
Double Strip or Grid Method
The searchers will traverse first parallel to the base and then parallel to the side.
Double Strip or Grid Method
The searchers follow each other in the path in the spiral manner beginning from the center

Spiral Method
The searchers gather at the center and proceed outwards along radii or spokes.
Wheel/ Ray Method
Whole area is divided into subdivisions or quadrants and search is made in the individual
quadrants.
