Lower Range
(2D Sonar, 2D Zoom, 2D Big Digits Views Only)
Lower Range sets the deepest depth range that will be displayed, and is only available on
the X-Press™ Menu when you are in the 2D Sonar, 2D Zoom, or 2D Big Digits Views.
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™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Lower
Range setting. (AUTO, 10 to 1000 feet, 3 to 330 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.
