Fishnder scrolling
The shnder image scrolls from right to left. You can adjust or
pause the scrolling, for example to ease placing of waypoints or
VRMs on-screen.
Scroll speed
You can adjust the speed at which the shnder image scrolls. A
faster speed provides more detail which may be useful when you
are looking for sh. If you select a slower speed the information
remains on the display for longer.
The following option is available:
• Manual. This allows you to set the scroll speed as a percentage of
the maximum scroll rate for that depth. The lower the percentage,
the slower the image will scroll. The default setting is 100%.
Scroll pause
You can pause the display to see a ‘snapshot’ of the shnder
image. When the image is paused scrolling stops but the depth
indication continues to be updated. Scroll pause/resume affects the
currently selected shnder frequency.
If you are in dual frequency mode, you can pause one frequency
while the other continues to scroll. This allows you to inspect a
paused image while the other frequency continues to scroll and
detect sh.
Note: Scrolling will resume if the frequency changes. For
example an automatic change of frequency resulting from a
change in depth.
