Fishfinder Range - Raymarine a series Installation And Operation Instructions Manual

Bottom Lock
The Bottom Lock function applies a filter to flatten the image of
the seabed and make any objects on or just above it easier to
see. This feature is particularly useful for finding fish that feed
close to the bottom.
Adjusting the range of the bottom lock image allows you to view
more bottom details. You can also reposition the image on
screen to anywhere between the bottom of the window (0%) and
the middle of the window (50%) by using the Bottom Shift control.
