4.3Picture 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: Match the picture advance speed to that of the echo sounder. This setting does not affect original echosounder setting.

1.Press the [MENU] key to open the menu.

2.Use the [RANGE] control to choose [MENU MODE] at the top of the screen.

3.Use the [GAIN] control to choose SOUNDER.

4.Use the [RANGE] control to choose ADVANCE.

5.The picture advance speed setting is locked so use the [GAIN] control to choose YES and then press the [EVENT] key.

6.Use the [GAIN] control to adjust advance speed desired. 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.

7.Press the [MENU] key to close the menu.
