5. ECHO SOUNDER MODE

5.6Picture 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.
