USING THE TRACKER UNIT
MENU FUNCTIONS
Fish ID. There are three selections available: OFF, ID+ ON, and ADJUST. The fac- tory 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 Tracker unit 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 Tracker unit 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.
Increasing the value to a number greater than 
zero shows more fish symbols
this case smaller sonar returns will be depicted
as fish symbols. This is useful for identifying
many smaller sonar returns (such as baitfish)
as fish symbols.
Decreasing the value to a number less than zero
shows fewer fish symbols
smaller sonar returns are disregarded. This is
useful for eliminating many small sonar returns 
when seeking larger species of fish.
