Picture advance speed setting window
The fractions in the window mean the number of vertical scan lines produced per transmission.
For example, “1/2” means a vertical scan line is produced every two transmissions. These
fractions also appear at the top of the screen for your reference.
When selecting an advance speed, keep in mind that a fast advance speed will expand the size
of a fish school horizontally and a slow speed will contract it. The current speed appears at the
top of the display.
1/1 S
"S" means picture advance
speed is synchronized with
ship's speed.
