2.10 Omni / Echosounder (Option)
Figure 14 - Omn i / Echo sounder
The Omni / Echosounder mode is also specially made for
trawling, but in this mode the trawl- locked vertical slice is
replaced by an echo sounder recording. This to ensure a more
correct depth indication in case the sonar beam is bent because of
temperature layers.
In order to get the school presented in the echo sounderrecording,
the vessel must here pass over the target.
