Performance Steps
Note: Slow scan search technique uses the same process as the rapid scan but with more
intent; this means a slower, side-to-side movement and more frequent pauses.
(3) Use detailed search technique (figure 071-331-0804-5).
Figure 071-331-0804-5. Detailed
Note: The detailed search is like the slow scan, but searching smaller areas with frequent
pauses and almost incremental movement.
b. Conduct a visual search in limited visibility.

one of the following:

minutes in darkness, if applicable.
