Picture Advance Speed

The picture advance speed determines how quickly the vertical scan lines run
across the screen. When selecting a picture advance speed, keep in mind that a
fast advance speed will expand the size of the fish school horizontally on the
screen and a slow advance speed will contract it.
The advancement speed may be set independent of or synchronized with ship's
speed.
