2D Sonar
Display the RTS Window
The RTS Window plots the depth and intensity of a sonar return. It updates at the fastest rate possible for depth conditions and
shows only the returns from the bottom, structure, and fish that are within the transducer beam. When you use the cursor to review
s
onar history, the sonar history will pause, but the RTS Window will continue to display sonar returns in real time.
1. From the Preferences menu, select RTS Window.
2. Tap the on/off button, or press the ENTER key, to turn it on. Then, choose the type of RTS Window to display.
Turn on/off Fish ID+
Fish ID+ uses advanced signal processing to interpret sonar returns. When Fish ID+ is selected, fish symbols will be displayed on
the Sonar View when very selective requirements are met.
When Fish ID+ is not selected, the control head shows only the raw sonar returns on the display. The returns appear as arches on
the display to indicate potential targets.
1. From the Preferences menu, select Fish ID+.
2. Use the following menu options to display fish icons, adjust the sensitivity, and more.
Color (A-Scope)
Sonar returns are displayed in color. The size of the displayed lines correspond with the
intensity of the sonar returns from the transducer beam(s).
Color (Full) Sonar returns are displayed in color, and they fill the width of the RTS Window.
Mono Sonar returns are displayed in black.
Fish Icons
Select Fish Icons to display fish symbols on the 2D Sonar View when a fish is detected.
Blue Fish Icons = targets detected in the 200 kHz narrow beam.
Orange Fish Icons = targets detected in the 83 kHz or 50 kHz wide beam.
Fish Depth The depth of the fish is displayed above the fish icon.
ID Sensitivity
Use ID Sensitivity to adjust the threshold used for detecting a sh with Fish ID+. (1 = low
sensitivity, where only a large fish will be displayed, and 10 = high sensitivity, where small fish
up to large fish will be displayed)
Fish Alerts To receive an on-screen alert when a fish is detected, turn on this menu option.
