Sensitivity:
Controls how much detail is shown on the display. When
operating in very clear water or greater depths, increased sensitivity
shows weaker returns that may be of interest. Decreasing the
sensitivity eliminates the clutter from the display that is sometimes
present in murky or muddy water.
(1 to 20, where Low = 1, High = 20;
Default = 10)
NOTE:
The Sensitivity can be adjusted from the DI Enhance dialog box or the Down
Imaging™ X-Press™ Menu. The Sensitivity setting is provided here so that you can
easily adjust the Down Imaging™ data with the other settings. See
Down

Upper Range
(Advanced, Down Imaging
™
Views only)
Settings: 0 to 1490 feet or 0 to 497 meters
[International models only], Default = 0
Upper Range
sets the shallowest depth range that will be displayed on the
Down Imaging™ 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.
Lower Range
Settings: Auto to 1500 feet, Auto to 500 meters
[International Models only]; Default = Auto
Lower Range
sets the deepest depth range that will be displayed by the unit.
Auto:
The Lower Range will be adjusted by the unit to follow the bottom
automatically. Auto is the default setting.
Manual:
You can adjust the Lower Range to lock the unit on a particular
depth.
will be displayed in the lower right corner of the screen to
indicate the unit is in Manual mode. Adjust the Upper and Lower Range
together to view a specific depth range, especially when looking for fish or
bottom structure.
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,
which allows 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 Down Imaging™ 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.
