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 choosing 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.
1/1 S "S" means picture advance speed is
synchronized with ship's speed.
