White line

The white line is an extra thick white line that is added to just below the bottom. The
white line will not remove information, it will simply "push" the information further
down in order to make the bottom easier to see.
Most users find it practical to use the white line all the time. If the echo sounder should
loose bottom track – for example due to the appearance of a large school of fish – you
will immediately see this on the white line.
The white line is enabled in the
