grouping of black horizontal lines, typically
having gray lines underneath. A harder
bottom shows less gray below; a soft
bottom shows more gray below. Structure
appears above the bottom as a cluster of
lines with varying lengths and gray shades.
Fish appear as smaller groupings of sonar
returns between the bottom and surface.
Often, large fish within structure will
show as a strong return within a grouping
of smaller returns. When the boat is
stationary or drifting very slowly, the RTS
window can show the movement of the fish through the transducer beam.
Moving fish appear as smaller groups of lines progressively become larger
lines, or vice versa. A grouping of lines moving vertically indicates a fish
changing depth.
The width of the RTS window can be adjusted to your preference.
Selecting a wider RTS window shows greater differences between
the strength of the sonar returns; however it reduces the amount
of history on the display. See C

to form an image of the bottom contour.
The most recent sonar returns are charted
on the right side of the window; as new

information is moved across the display.
The chart window also indicates the
composition of the bottom. A hard bottom
such as compacted sediment or flat rock
appears as a dark, thin line across the
