Upper Range
2D Sonar, or 3D/2D Combo View when
2D Sonar side is active only)
Upper Range
sets the shallowest depth range that will be displayed on the
2D Sonar View, or 3D/2D Combo View when the 2D Sonar side is active. 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 2D
Sonar View, or 3D/2D Combo View when the 2D Sonar side is active. 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 2D Sonar X-Press™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or
decrease the Upper Range setting. (0 to 990 feet; 0 to 327 meters
[International models only]
, Default = 0)
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 settings entered manually.
To adjust the Lower Range:
1. Highlight Lower Range on the 2D 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.

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.
