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 

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

3000 S

ERIES

changes the depth range to
keep the bottom on-screen. The 

L

EGEND

3000 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

3000

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

3000 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.
