White Line
W HITE L INE activates and
adjusts a feature
which changes how
the
L EGEND 2000 S ERIES
draws the bottom
contour and
structure, and also
shows fainter sonar
returns more clearly.
When a
W HITE L INE
setting of 1 to 8 is
selected, a light gray
band highlights the
strongest sonar returns within the sonar image
and makes a distinctive outline along the
bottom contour, structure and fish. Selecting a
larger numeric setting increases the width of the
band and makes fainter sonar returns more
noticeable, but the
L EGEND 2000’ S
ability to show
subtle differences in bottom composition and
structure is reduced. Selecting a smaller
numeric setting narrows the band and shows
greater variation in bottom composition.
Selecting
O FF turns the W HITE L INE feature off.
The W HITE L INE setting is retained in memory after
the L EGEND 2000 S ERIES
is turned off. The factory
setting is O FF
.
Filter
F ILTER ( D EEP
Models only)
turns the filtering
algorithms on and off.
Select
O N
to filter excess sonar noise. Select O FF
to show the greatest amount of sonar
information.
The F ILTER setting is retained in memory after the
2000 Deep/2005 Deep is turned off. The factory
setting is O N
.
Depth Alarm
D EPTH A LARM activates a
shallow water depth
alarm. The alarm will
sound when the digital depth becomes equal to
or less than the setting. The tone sounds at a
rapid rate for several seconds and then sounds
intermittently until the boat moves to deeper
water. The
D EPTH A LARM can be muted by pressing
the C ONTROL P ANEL knob ; once muted, the alarm will
not sound again until the boat moves to water
deeper than the
D EPTH A LARM setting. International
models have Depth Alarm settings in metres
and fathoms
Note: Remember that depth is measured from the
transducer, not from the surface of the water.
The D EPTH A LARM
setting returns to factory default
after the L EGEND 2000 S ERIES is turned off. The factory
setting is O FF .
Temp Alarm
Temp Alarm activates
an alarm that sounds
when the surface water
temperature changes to fall within or outside
selected ranges. These temperature boundaries
help define bodies of water that are comfortable
for and or are feeding zones for fish. Upper and
lower temperatures are set depending on the
species of fish being sought. Two basic actions
can be selected to trigger an alarm, either
entering inside a temperature range or exiting –
moving outside a temperature range. Both
combines Inside and Outside settings, alarming
when crossing a temperature boundary. The
Temp Alarm can be muted by pressing the
Control Panel knob; once muted, the alarm will
not sound again until triggered by a new
boundary crossing.
The T EMP A LARM setting returns to factory default
after the L EGEND 2000 S ERIES
is turned off. The factory
setting is O FF
.
Note: You must select a Temp Alarm mode (I NSIDE ,
O UTSIDE , or B OTH ), then set the U PPER T EMP and the L OWER
T EMP in order for this feature to work.
