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, especially while moving or trolling. A lower scroll speed displays sonar information on the screen longer. Setting the scroll speed on one sonar view applies to all the sonar views.
-
From a sonar view, select
> Sonar Setup > Scroll Speed.
-
Select an option:
-
To adjust the scroll speed automatically using speed-over-ground, 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, it is recommend to use the Auto setting.
-
To use a very fast scroll speed, select Ultrascroll®.
The Ultrascroll option quickly scrolls new sonar data, but with a reduced image quality. For most situations, the Fast option provides a good balance between a quickly scrolling image and targets that are less distorted.
