Sonar Views (Deep Models Only)
The dual beam (50/200kHz) sonar information can be
displayed in several different views in the
C HART W INDOW
. In the
200kHz view, only the sonar returns and F ISH ID from the
200kHz beam are displayed. Typically, the 200kHz
information provides greater bottom detail up to 800' and
works well while the boat is in motion. The 50kHz view only
shows the sonar returns and
F ISH ID from the 50kHz beam.
The 50kHz information provides depth accuracy up to 2000'
and shows more targets in its wider beam. The Split Screen
view shows the 50kHz and 200kHz sonar information in
side-by-side windows on the display. The 200kHz/50kHz
view is a composite of the 200kHz sonar information and
the target information from the 50kHz sonar. See
CONTROL
PANELS for details on selecting the sonar views.
CONTROL PANELS
Control Panels provide
access to important,
but infrequently-
adjusted features, such
as
C HART S PEED , M ODE , S ONAR
V IEW , L IGHT , C ONTRAST , RTS
W INDOW , S URFACE C LUTTER , W HITE L INE ,
F ILTER , D EPTH A LARM , T EMP A LARM , F ISH
A LARM , F ISH S ENSITIVITY , F ISH ID,
S IMULATOR , U NITS , and, in
International Models only,
L ANGUAGE
. Control Panels allow
you to set the mode of
operation as well as
additional features. Use the
M ODE to change the bottom
tracking and depth range
method of display, then use
the other Control Panels to
add features to your
selected mode of operation.
Note: Only the International Models (2005 and 2005 Deep)
contain a Language choice in the Control Panel, and only
the International Models support multiple units of measure,
such as fathoms and metres.
Note: The Sonar View, Fish ID, Fish Alarm, Fish Sensitivity, and
Filter choices only appear on the Deep Model Control Panels.
C ONTROL P ANELS
are displayed by using the C ONTROL P ANEL knob
and adjusted by using the R ANGE
knob. The active
C ONTROL P ANEL consists of three parts: the C ONTROL P ANEL N AME ,
S ETTING I NDICATOR
, and S ETTING R EADOUT
.
The C ONTROL P ANEL N AME indicates the feature, the S ETTING
I NDICATOR shows the current setting within the complete
range of adjustment, and the S ETTING R EADOUT
shows the
status when C ONTROL P ANEL is not selected.
To select a C ONTROL P ANEL
feature for adjustment, follow
these steps:
1. Press the C ONTROL P ANEL knob . A list of options appears on the
display. The option currently selected for adjustment is indicated
by a white background color.
2. Rotate the C ONTROL P ANEL knob to select the desired option for
adjustment. Clockwise rotation selects options higher in the list;
counterclockwise rotation selects options lower in the list.
Note: Not all options in the list can be viewed on the display at
one time. When the selected option is at the bottom of the list,
continue turning the knob to display other options.
3. Once the desired option is selected, turn the R ANGE knob to adjust.
Adjustments are made immediately and are shown by an indicator on
the selected C
ONTROL P ANEL .
4. Remove the C ONTROL P ANELS by pushing the C ONTROL P ANEL knob .
Alternately, after a few seconds with no knob press/turn activity, the
C
ONTROL P ANELS are removed from the display automatically.
Mode
The first Control Panel to set
is Mode. Three modes of
operation control the
method used by the Legend
2000 Series to track the bottom, select depth ranges
and graph the information on the LCD display. The
Mode is selected by changing the Control Panel
setting to Auto, Manual, or Btm Lock (Bottom Lock).
Automatic Mode
A UTOMATIC M ODE
follows the bottom contour, changing
depth ranges as needed to keep the most recent sonar
returns visible on the display.
A UTOMATIC M ODE
keeps the
acquired bottom visible at all times, showing sonar
returns from the surface to the bottom. This is done in
the top ²⁄₃ of the display to reduce range changes and
is useful when traveling across the water in areas
where the depth constantly changes.
In Automatic mode, the Legend 2000 Series 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.
