TILT ANGLE SETTINGS
Selecting the proper “Tilt Angle” for surface or bottom fish echoes will depend on the
Tilt Angle you have selected. The recommended tilt angle for surface fish should be
a narrow angle approximately (5 degrees) and for bottom fish, a wide angle
approximately (30 degrees)
5.5.1 Discriminating Fish Echoes
•
Tilt angle 0 degree to 8 degrees:
Using this tilt angle, you may or may not capture the bottom since the returned
echoes are weak.
•
Tilt angle 10 degrees to 20 degrees
Using this tilt angle, you will only display half of the bottom since the lower halves
of the sonar beam only capture it.
•
Tilt angle 20 degrees to 40 degrees
Using this tilt angle, you will display the entire bottom since the full width of the
beam is captured.
