When ship passes over schools of fish
The sounding beam is directed fore-aft and the display is offcentered* to present a
wider view of the area forward of the ship. You can clearly see the schools of fish ap-
proaching from the bow of the ship.
*: Automatically shifted according to the operation control settings.

Display of net hauling
The net hauling display is useful for raising the net at the right time.
3.13.5
False echo
In shallow water (less than 100 m), unwanted echoes may appear. This phenomenon
is caused by the false echo from the previous transmission. Reducing the Tx rate on
the BOTTOM/3D menu may lessen this effect.
