10.9 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 the fish school horizontally on the screen and a slow ad-
vance speed will contract it.

The fractions in the window denote the number of scan lines produced per trans-
mission. For example, 1/8 means one scan line is produced every eight transmis-
sions. STOP freezes the display and it is convenient for taking a picture of the
display.
4. Push the [ENTER] knob and [MENU] key in order to close the menu.
Note: When using a plotter/sounder combination display, advancement of the sound-
er picture may be temporarily interrupted while the plotter display is being shifted or
its display range is being changed.
