USING THE 450TX
MENU FUNCTIONS
This gives the user easiest recognition of the bottom location, even from a great distance.
The 450TX remembers the Bottom Black setting when powered off.
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 450TX 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 which beam the fish is detected in. The 450TX 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 on- screen. In 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
