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.
1. Open the home screen, then tap [Settings] - [Sounder].
2. Tap [Picture Advance].
3. Tap a picture advance speed. The options in the window indicate the number of
scan lines made per transmission. For example, [1/2] creates one scan line per
two transmissions. [1/16] is the slowest advance speed and [4/1] is the fastest
speed. [Stop] stops picture advance, and is useful for taking a photo or screenshot
of the screen.
