2.2 Changing of Image Speed
The image speed of echo sounder can be
changed. Even if the schools of fish and bottom
are same, the image changes depending on the
image speed.
The setting of image speed is shown by the
comparison with the normal image speed “1/1”.
“2/1” image speed is two times the normal
image speed. “1/2” is a half time the normal
image speed. When “Stop” is selected, the
image speed is stopped.

2.3 Rejection of Interference
Interference Rejection
The interference noise from the echo sounder
of other boats can be reduced.
If a neighboring boat uses the echo sounder
having the same frequency and same firing
times as those your boat has, the interference
noise may be displayed. If you set the
interference rejection, the interference noise
can be reduced. In the order of weak
→

the noise rejection capability becomes high.
