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 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.

Upper Range
(Advanced: Sonar, Split Sonar, Big Digits and Circular Flasher Views only)
Upper Range sets the shallowest depth range that will be displayed on the Sonar,
Split Sonar, Big Digits and Circular Flasher views. The Upper Range menu choice is
available when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and
can only be accessed from the Sonar, Split Sonar, Big Digits and Circular Flasher
views. Upper Range is often used with Lower Range.
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 Upper Range:
1. Make sure you are in Advanced Mode, then highlight Upper Range on the
Sonar X-Press
TM
Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the
Upper Range setting. (0 to 990 feet or 0 to 327 meters [International Models
only], Default = 0)
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), and
will show greater detail for that area between 20 and 50 feet.
