Humminbird Legend 1000 - Manual (Page 9)

In A UTOMATIC mode, the L EGEND
1000 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 1000
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 1000 Series is operating in
Automatic Mode.
2. Push the R ANGE knob. An adjustment indicator
appears at the lower right corner of the C HART W INDOW .
3. Turn the R ANGE
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 L EGEND 1000 S ERIES
changes the depth range to keep the bottom on-screen. The
L EGEND 1000 S ERIES
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 L EGEND 1000 S ERIES
is operating in
Automatic.
2. Push the R ANGE knob. An adjustment indicator
appears at the lower right corner of the C HART W INDOW .
3. Turn the R ANGE
knob clockwise until the second return
is visible on the display.
4. To return the depth range to normal viewing, rotate
the R ANGE 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 1000 S ERIES 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.
