Lower Range
Lower Range sets the deepest depth range that will be
displayed. Automatic is the default setting. When in automatic mode, the lower range
will be adjusted by the unit to follow the bottom. Selecting a specific setting locks the
depth range into Manual mode. Use both Upper and Lower Range together to view a
specific depth range manually when looking for fish or bottom structure.
will be
displayed in the lower right corner of the screen when you start manually adjusting the
Lower Range to indicate that you are in Manual mode.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower
Range regardless of the manual settings entered.
To adjust the Lower Range:
1. Highlight Lower Range on the Sonar X-Press TM menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease
the Lower Range setting. (AUTO, 10 to 600 feet, 3 to 240 meters
[International Models only], Default = AUTO)
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,
allowing you to see a more detailed view than you would see if the
display went all the way to the bottom.
