This shows a split display, with the sonar history
on the right side and the zoom section on the
left. The bottom signal is shown as a

at trace
in the centre of the zoom section.
Showing the bottom as a
ß
at trace can make it
easy to compare the echo strengths shown in the
bottom signals. This can help to identify the type
of bottom and objects close to the bottom.
The zoom bar can only indicate the zoom range.
It cannot indicate the zoom offset as this changes
for each sounding displayed on the display. The
zoom bar is
Þ
xed in the middle of the display.
See section 4-4 Range, for information about
adjusting the Zoom Range and Zoom Offset.
