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 school of fish 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. 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" dis-
plays one scan line per two transmissions.
6. Press the
MENU
key to close the menu.

trackball mark changes to a cross-hair cursor.
2. Adjust the trackball to place the cross-hair cursor at the location desired.
3. Read the depth to the location at the cross-hair cursor.
