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 1000 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.
U PPER T EMP
is the upper
temperature boundary for the
temperature alarm. The inside
temp alarm will sound when
the water temperature was initially above the upper
temp boundary and then falls below it. The outside
temp alarm will sound when the water temperature
was initially below the temp boundary and then rises
above it.
The U PPER T EMP setting is retained in memory after the L EGEND
1000 S ERIES
is turned off. The factory setting is 78 ° F/ 26° C.
L OWER T EMP
is the lower
temperature boundary for the
temperature alarm. The inside
temp alarm will sound when
the water temperature was initially below the lower
temp boundary and then rises above it. The outside
temp alarm will sound when the water temperature
was initially above the temp boundary and then falls
below it.
The L OWER T EMP
setting is retained in memory after the
Legend 1000 Series is turned off. The factory setting
is
72 ° F/ 22° C.
Fish Alarm
F ISH A LARM
(Deep Models only)
will sound when a fish (or
other target not connected to
the bottom) that meets the selected size criteria is
detected by the sonar. The
F ISH A LARM
has four different
settings, O FF plus the three different fish symbols
shown onscreen (see F ISH ID ). The 1000 Deep/1005 Deep can
be set to alarm only large fish, (displayed as a large
fish symbol), only large and medium fish (displayed as
one large and one medium fish symbol), or all sizes of
fish (displayed as one large, one medium, and one
small fish symbol).
The F ISH A LARM
setting is retained in memory after the 1000
Deep/1005 Deep is turned off. The factory setting is O FF
.
Fish Sensitivity
F ISH S ENSITIVITY
(Deep Models
only) adjusts the sensitivity of
the fish detection algorithms
separately from the sonar gain
control knob. Selecting a positive offset makes the
fish detection more sensitive (+5 = greatest
sensitivity). Selecting a negative offset makes the fish
detection less sensitive (-5 = least sensitivity).
The F ISH S ENSITIVITY
setting is retained in memory after the
1000 Deep/1005 Deep is turned off. The factory setting is 0 .
Fish ID
F ISH ID (Deep Models only) uses
advanced signal processing to
evaluate further any sonar
return between the surface and the bottom. If the
return meets certain additional criteria, a fish symbol
will be assigned. There are three different fish symbols
to indicate the intensity of the sonar return. While
signal intensity is a good indicator of fish size,
different species of fish have different sonar
characteristics, so it is not always possible to
distinguish fish size amongst varying species.
Selecting
F RESHWATER
will adjust the algorithms toward
freshwater species of fish, while selecting S ALTWATER
will
adjust the algorithms towards saltwater species.
Note: The signal intensity is “normalized” for depth so that a
small fish close to the boat will not appear as a large fish
symbol. The digital depth of the designated fish is also shown
to help locate the fish vertically. This is especially helpful in
setting bait depths or for downrigger operation.
The F ISH ID setting is retained in memory after the 1000
D EEP /1005 D EEP
is turned off. The factory setting is Off.
