4.3 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:
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.
4.4 Measuring
Depth
You can measure depth to the cross-hair cursor as follows:
1. Use the trackball to place the trackball mark inside the echosounder display.
The 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.
