NOTE:
A minimum distance of 10 feet will be maintained between the Upper and
Lower Range regardless of the manual settings entered.
The available Upper Range settings are determined by your Humminbird® model
as follows:
•
788ci HD:
0 to 1490 ft, 0 to 497 m (International Models only);
Default = 0
•
788ci HD DI:
0 to 1490 ft, 0 to 497 m (International Models only);
Default = 0
•
788ci HD XD:
0 to 3190 ft, 0 to 972 m (International Models only);
Default = 0
Lower Range
Settings: Various, see below.
Lower Range
sets the deepest depth range that will be displayed by the unit.
Auto:
The Lower Range will be adjusted by the unit to follow the bottom
automatically. Auto is the default setting.
Manual:
You can adjust the Lower Range to lock the unit on a particular depth.
“M” will be displayed in the lower right corner of the screen to indicate the unit
is in Manual mode. Adjust the Upper and Lower Range together to view a
specific depth range, especially when looking for fish or bottom structure.
For example, if you are only interested in the area between 20 and 50 feet deep,
you should set the Upper Depth Range to 20 and the Lower Depth Range to 50.
The Sonar View will then show the 30 foot area between 20 and 50 and will not
show the surface or the bottom (assuming the bottom is deeper than 50 feet).
Greater detail will be shown for the area between 20 and 50 feet.
For example, if you are fishing in 60 feet of water but are only interested in the
first 30 feet (surface to a depth of 30 feet), you should set the Lower Depth
Range limit to 30. The display will show the 0 to 30 foot range, which allows you
to see a more detailed view than you would see if the display went all the way
to the bottom.
