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 3000 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 3000 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 3000 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 3000 Deep/3005 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
3000 Deep/3005 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
3000 Deep/3005 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,
