5. ECHO SOUNDER MODE
5-11
5.6 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 a fish school horizontally and a slow advance
speed will contract it.
Note: Set the picture advance speed to the same setting as on the echo sounder
connected. This setting does not affect the original echo sounder setting.

5. Use the trackball to select advance speed desired and press the [MENU] key.
The fractions in the dialog box are one line produced per number of
transmissions. For example, 1/2, displays one scan line per two
transmissions. SPEED SYNC advances the picture according to ship’s speed.
This mode is advantageous for judging fish school size and abundance since
fish schools will be shown at their actual sizes regardless of ship’s speed.
Note: When using “SPEED SYNC,” and the echo sounder signal becomes
lost, the picture shown at the time the signal was lost is copied and
continuously replayed on the screen until the echo sounder signal is
restored.
