Fish Alarm
The Fish Alarm alerts you to the presence of fish, or other targets not attached to the
bottom, in the water beneath your boat. The Fish Alarm has 3 different settings which correspond
to the 3 different size fish targets shown on-screen.
To enable Fish Alarm, use the UP and DOWN arrow buttons to adjust the size return you
want to be alerted to: large fish only, large and medium size fish, or all fish. To disable the alarm
use the UP button to return to the off position.
Remember that it is
impossible for sonar to determine if
a signal return is a fish or some
other type of object or suspended
debris. Any object not connected to
the bottom is normally a fish and is
portrayed as a fish symbol. The
strength of the reflected sonar
signal from a target is a good
indicator of the size of the target,
and the fish symbol displayed
represents the strength of the signal
reflected from it.
ID
ID is the automatic identification of target returns based on the strength of the returned signal and
other factors. Three options are available: ID "On" displays targets as one of three different size
fish symbols.
ID+", the default setting, provides more information about the location of the target by
attaching depth "strings" showing the digital depth of the target. When there are numerous targets
onscreen, not every target depth is shown, to avoid excessive clutter onscreen.
