1.11 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
advance speed will contract the school. Use a fast advance speed to observe a rug-
ged bottom, and use a slow advance speed to monitor a smooth bottom.
Note: When ACCU-FISH™ or Bottom Discrimination function is in use, the image feed
speed may slow down.
