1.10 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 a school of fish
horizontally on the screen and a slow ad-
vance speed will contract the school. Use a
fast advance speed to observe a rugged bot-
tom, and use a slow advance speed to moni-
tor a smooth bottom.
