In A
UTOMATIC
mode, the L
EGEND
3000 S
ERIES
selects the depth
range best suited to keep recent sonar returns visible;
however, the depth range can be adjusted to optimize
the display for viewing the second return. The display
can also be optimized for maximum display resolution,
making it possible to distinguish fish very close together
or close to the bottom.
Optimizing the Depth Range for Sonar Targets
When the image of the bottom does not appear close
to the bottom of the LCD display, the Legend 3000
Series is not fully
optimizing the display to
show sonar targets, such
as fish, that are very close
together. To enhance the
ability of the unit to
separate sonar targets and
to optimize the display for
maximum resolution, follow
these steps:
1. Make sure the Legend
3000 Series is operating
in Automatic Mode.
2. Push the RANGE knob. An
adjustment indicator
appears at the lower
right corner of the CHART
WINDOW.
3. Turn the RANGE knob
counterclockwise until
the image of bottom is
close to the bottom of
the LCD display but still
shows the area of
interest.
Note: As the depth of the water
increases, the
LEGEND 3000 SERIES
changes the depth range to
keep the bottom on-screen. The
LEGEND 3000 SERIES uses a depth
range to keep the bottom contour close to the bottom of the
display.
To return the depth range to normal viewing, turn the
unit off and back on again using the G
AIN
knob. This is
the only way to reset the depth range to normal
viewing.
Optimizing the Depth
Range for Second Return
To optimize the depth
range for viewing the
second return, follow these
steps.
1. Make sure the LEGEND 3000
S
ERIES is operating in
Automatic.
2. Push the R
ANGE
knob. An
adjustment indicator
appears at the lower right
corner of the CHART WINDOW.
3. Turn the RANGE knob
clockwise until the
second return is visible
on the display.
4. To return the depth range to normal viewing, rotate
the RANGE knob counterclockwise until the depth
range stops updating.
Note:The second return does not appear at many of the deeper
depth ranges. The appearance of the second return depends
on depth of the water, water conditions, bottom hardness and
the gain setting.
The L
EGEND 3000 SERIES
operates with this offset depth
range until it is returned to the original settings, or the
unit is turned off, after which the unit defaults to
factory settings.
