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.

setting.
