Intermec PRO 128 Fish Finder User Manual


 
There are three different size fish sym-
bols used to indicate the intensity of the
sonar return. While signal intensity is a
good indicator of relative fish size, differ-
ent species of fish have different sonar
characteristics, so it is not always possi-
ble to distinguish fish size between vary-
ing species. The signal intensity is "nor-
malized" for depth so that a small fish
close to the boat does not appear as a
large fish symbol.
ID+ adds an additional piece of informa-
tion to help the user locate fish. On
selected fish symbols, the digital depth
of the designated fish is drawn to help
locate the fish vertically. This is especially
helpful in setting bait depths or for downrigger operation.
The fish symbols indicate the sonar beam the fish is detected in. This
gives you a reliable indicator of side to side location of the fish relative to
the boat. Fish symbols that are hollow are detected in the wide beam and
are around the boat. Solid fish symbols represent fish detected in the nar-
row beam and are directly under the boat.
