7.5 Picture Advance Speed
The picture advance speed controls how quickly the vertical scan lines move across
the screen. A fast advance speed expands the size of a school of fish horizontally on
the screen. A slow advance speed shortens the school of fish. Use a fast advance
speed to see the hard bottom. Use a slow advance speed to see the smooth bottom.

4. Use the RotoKey to select a picture advance speed. The options in the window
indicate the number of scan lines made per transmission. For example, "1/2" cre-
ates one scan line per two transmissions. 1/16 is the slowest advance speed and
4/1 is the fastest speed. "Stop" stops picture advance, so that you can take a pho-
to of the screen.
