Sensitivity
Controls the level of detail shown on the display.
Too much detail will clutter the screen. If Sensi-
tivity is set too low, desired echoes may not be
displayed.
Colorline
Helps distinguish fish or structure from the
bottom by showing hard returns as light colors
and soft returns as darker colors. A lower colorline
setting will display only the hardest returns,
shown in light colors.
Auto sensitivity
Keeps sensitivity at a level that works well under
most conditions, reducing the needs for adjust-
ments. Auto Sensitivity is turned on by default.
NOTE:
You can make minor (+/-40%)
changes to sensitivity with Auto
Sensitivity turned on. You will have to turn
it off to make significant adjustments.
Range
Selects the deepest range shown on
the display. Range settings display
the section of the water column from
the water surface to the selected
depth range.
If you select too shallow a depth range, the unit
will not be able to lock onto the bottom.
Custom range — Upper and Lower limits
Used to select the upper limit and lower limit of
a section of the water column. That allows you to
view a section of the water column that does not
include the water surface or the bottom. Upper
and lower limits must be at least 6.5 ft (2 m) apart.
