Upper Range
(Advanced: Sonar, Split Sonar and Active Sonar Side Views only)
Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split Sonar and Active
Sonar Side 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 and Active Sonar
Side 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™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Upper Range
setting. (0 to 1490 or 0 to 497 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 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 1500 feet; 3 to 500 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.
M
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.
