Grid Search Tips

Setting up a grid facilitates a search effort by subdividing the area to be searched. This allows searchers to systematically search the area one subdivision at a time. Grid searches prevent redundant effort and set up a framework for division of labor other search methods lack.

  1. Defining the Lines

    • If possible, use plainly visible terrain features to define your subdivisions. Streets, fence lines and power lines are excellent examples. Keep in mind that your "grid" doesn't need to be divided into squares. Rivers, winding roads and tree lines make good dividing lines even though the lines aren't straight.

    Grid Size

    • Make each grid sector small enough for one person or team to search in twenty minutes to an hour. This allows the entire area to be searched before a searcher becomes fatigued.

    Be Systematic

    • Search the grid systematically, moving from one side to another or outward from a central point. This reduces mistakes and makes it harder for a search subject to move from one grid sector to another unnoticed. If certain grid sectors are more likely candidates than others, start from those sectors and move outward rather than leapfrogging to disparate sectors.

    Set Up Shifts

    • If the search area is too large for each grid sector to be searched by a separate team, arrange for shifts to take turns searching. Fatigue can mean missing vital clues or even passing the search object by completely. Allow for adequate rests between searching forays.

    Ribbons and Markers

    • If unable to use natural markers to indicate grid lines, you can use tape, ribbon or string to mark the grid areas. Plant a series of stakes on each outside edge of your search area and connect opposite stakes with your string. This is most appropriate for smaller-area searches that must be gone over in detail.

    Sweep or Line Searches

    • If you have enough manpower, you can conduct a sweep or line search. Have members of the search team form a line on one edge of the grid, spaced so that each member can see the team members on either side. Have the team walk forward in a line, searching the in front and to either side of them.
