1.8Choosing Picture Advance Speed
The picture advance speed determines how quickly the vertical scan lines run across the screen. When choosing 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. Note that the picture is not refreshed when picture advancement is stopped. Therefore, use caution when steering the vessel under this condition.
