Bottom lock and bottom shift
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 discern.
This feature is particularly useful for finding fish that feed close to
the bottom.
Bottom Lock is selected for individual fishfinder windows and can
replace or appear alongside the standard fishfinder image.
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.
To adjust bottom lock
1. Toggle to FULL or SPLIT.
2. Use the appropriate softkeys and trackpad to set the range and
bottom-shift values.
