Graph Tab

Allows you to determine the appearance of the scrolling graph display and contains the unit settings that 

should not require frequent change. 

The following settings are available:

•    Fish Symbols —

 allows you to determine how the graph will display underwater targets and back-

ground information. If Fish Symbols are set to ‘Off’, the unit will display all of the available informa-
tion about the underwater environment. If a fi sh symbol is selected, the graph will display 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.

•     Scale —

 controls the depth ‘Scale’ displayed vertically along the right side of the graph. The  depth

‘Scale’ can be confi gured to display four different ways: as an ‘Overlay’, in the ‘Corners’, with ‘Basic’ 
or ‘No Scale’.
