Fish ID. There are three selections
available: OFF, ID
+
ON, and ADJUST. The
factory setting is ID
+
ON. With Fish ID
+
OFF, sonar returns are displayed as “raw”
information. There is no interpretation
made by the unit. Selecting ID
+
OFF also
disables the fish alarm.
ID
+
ON enables the 350TX to interpret the raw sonar data and, using a
variety of techniques, depict appropriate target returns as one of three
different size fish symbols. Further identification shows whether the fish is
in the wide or narrow beam. The
350TX also displays the depth
beneath the surface with the
corresponding fish symbol.
Selecting Adjust and making
incremental changes enhances the
fishfinder’s ability to identify sonar
returns as fish symbols.
