Structure

temperatures that appear at different depths

Fish
- The Fishfinder displays fish as arches
and/or fish icons, and can be set to alarm
when a fish of a certain size is detected.
When a target is detected, a Fish ID+™
symbol appears on the display with the
depth displayed above it. The size of the
symbol indicates the intensity of the sonar
return. The unit will clearly show schools of
Bait Fish as "clouds" of different shapes and
sizes, depending on the number of fish and
boat speed.

battery; can be set to alarm if the voltage falls
below a certain point.
