Scrolling speed
The standard sonar display is a scrolling bottom image, which shows a graphical
representation of the echoes seen by the sonar. New information appears at the
right hand side of the screen and scrolls to the left. The speed at which the display
scrolls is adjustable, but the same section of the bottom is displayed regardless of
the scrolling speed.
If you select a faster scroll speed, more detail is displayed, useful if you are looking
for fish, a slower scroll speed moves the information more slowly.
The sonar automatically adjusts the scroll speed, based on depth, but you can also
manually adjust the speed. If you select automatic adjustment, the scroll speed is
related to boat speed as follows:
• Less than, or equal to 0.5 kts, scroll speed is constant at 10%.
