If you want to highlight smaller fish targets or create a higher
intensity display of a target, you can increase the color gain or
contrast setting. This causes a loss in the differentiation of the
high intensity returns at the bottom. If you want to reduce the
intensity of the return, you can reduce the color gain or contrast.

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.
