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.
