Creeping Line / Parallel Line Search Pattern - Raymarine LIGHTHOUSE 3 Advanced Operation Instructions

Example

Creeping line / Parallel line search pattern

The Creeping / Parallel Line search pattern covers a rectangular area. The area is searched either
by starting at one end of the search area (Creeping), which provides greater coverage of one end
but will take time to cover the whole area, or by searching the area lengthways (Parallel). This
provides reasonable coverage of the area quickly.
The Creeping Line search should be used when there is a logical end of the search area to start
your search from.
