Setting the Scroll Speed

You can set the rate at which the sonar image moves across the
screen. A higher scroll speed shows more detail until there is no
additional detail to show, at which point it starts stretching out
the existing detail. This can be useful while moving or trolling, or
when you are in very deep water where the sonar is pinging very
slowly. A lower scroll speed displays sonar information on the
screen longer.
For most situations, the Default setting provides a good balance
between a quickly scrolling image and less distorted targets.
1 From a sonar view, select Menu > Sonar Setup > Scroll
Speed.
2
Select an option:
• To adjust the scroll speed automatically using speed-over-
ground or water speed data, select Auto.
The Auto setting selects a scroll rate to match the boat
speed, so targets in the water are drawn with the correct
aspect ratio and appear less distorted. When viewing
Garmin ClearVü or SideVü sonar views or searching for
structure, it is recommend to use the Auto setting.
• To scroll faster, select Up.
• To scroll more slowly, select Down.

Adjusting the Range of the Depth or Width Scale

You can adjust the range of the depth scale traditional and
Garmin ClearVü sonar views and the range of the width scale
for the SideVü sonar view.
Allowing the device to adjust the range automatically keeps the
bottom within the lower or outer third of the sonar screen, and
can be useful for tracking a bottom that has minimal or moderate
terrain changes.
Manually adjusting the range enables you to view a specified
range, which can be useful for tracking a bottom that has large
terrain changes, such as a drop-offs or cliffs. The bottom can
appear on the screen as long as it appears within the range you
have set.

From a sonar view, select Menu > Range.

Select an option:
• To allow the chartplotter to adjust the range automatically,
select Auto.
• To increase or decrease the range manually, select Up or
