1.16 Picture Advance Speed
The picture advance speed determines how quickly the vertical scan lines run across
the screen. When setting a picture advance speed, keep in mind that a fast advance
speed will expand echoes horizontally on the screen and a slow advance speed will
contract them. A fast advance speed is useful for observing the rugged bottom closely.
A slow advance speed is useful for observing the smooth bottom.
1. Press the MENU/ESC key, then open the [Setting], [External fish finder] or [Tele-
sounder] tab.
2. Select [Sounder], then push the ENTER knob.
3. Select [Pic. Advance], then push the ENTER knob.
4. Select the picture advance speed desired, then push the EN-
TER knob.
The fractions in the window indicate the number of scan lines
produced per transmission. "1/4" is the slowest speed and “×4”
is the fastest speed. "1/4" means one scan line is produced ev-
ery four transmissions. "Stop" freezes the display and is useful
for taking a photo of the display. The current picture advance speed appears at
the upper left side of the display.
5. Press the MENU/ESC key several times to close the menu.
