Lower Range - Humminbird 778c HD Operation Manual

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.
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 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.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and
Lower Range regardless of the manual settings entered.
The available Lower Range settings are determined by your Humminbird® model
as follows:
• 778c HD: Auto to 1500 ft, Auto to 500 m (International Models only);
Default = Auto
• 778c HD XD: Auto to 3200 ft, Auto to 975 m (International Models
only); Default = Auto
