range best suited to keep recent sonar returns visible;
however, the depth range can be adjusted to optimize
the display for viewing the second return. The display
can also be optimized for maximum display resolution,
making it possible to distinguish fish very close together
or close to the bottom.
Optimizing the Depth Range for Sonar Targets
When the image of the bottom does not appear close
to the bottom of the LCD display, the Legend 3000
Series is not fully
optimizing the display to
show sonar targets, such
as fish, that are very close
together. To enhance the
ability of the unit to
separate sonar targets and
to optimize the display for
maximum resolution, follow
these steps:
1. Make sure the Legend

in Automatic Mode.
