Sonar Tab Options
Fish Symbols — allows you to determine how the graph displays underwater targets and back-
ground information. If Fish Symbols are set to ‘Off’, the unit displays all of the available informa-
tion about the underwater environment. If a fi sh symbol is selected, the graph displays only the
information related to that symbol. Actual fi sh returns may not always appear as perfect arches
(like in simulator mode), due to the speed, fi sh orientation and/or other conditions.
