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 Options > 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/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.
