Changing the Fishfinder Range
The Fishfinder automatically adjusts the display range. Alternatively, the
RANGE
key lets you select the maximum depth displayed on the scrolling
bottom and A-scope displays. You can also set the shift value to move the
image window up or down within the current range.
If you select automatic range adjustment, the Fishfinder selects the shallowest
range that keeps the bottom in the lower half of the display window. Shift is
disabled (the value is ignored) when auto-range is selected.
The following range/shift values are available:
