Mark Description
Target Lock Mark The target lock mark automatically tracks the fish school selected
by the operator. This function requires speed and gyrocompass inputs.
Net Shooting Mark
Net Shooting Data
Press the SHOOT key at the instant you shoot the net to display the
net shooting mark on the display. The net shooting mark is drawn
at own ship’s position the moment the key is pressed and moves on the
own ship’s track mark with ship’s movement. In addition to the
mark, time elapsed and *distance run (in meters) appear from the
time the key is pressed. The mark and its data remain on the screen
until the SHOOT key is pressed again.
Net Sonde Mark
(10 pts. max)
These marks appear on the *ship’s track mark in order at set intervals,
when a net sonde is connected. In the echo sounder combination
mode they also appear in the echo sounder picture, showing depth of
the net sonde transmitters with bars extending vertically from the marks.
E/S Picture Advance
Range Data
Picture advance on the echo sounder combination mode automatically
changes to ship’s speed dependent (advance) rate from the moment
the SHOOT key is pressed, provided there is speed log input. The
E/S picture advance range data shows the distance between the right
and left edges of the echo sounder picture window in the ship’s speed
dependent advance. Since the net length plus wire length set on the
DATA SET menu is used as this distance data, the echograms
obtained during casting the net are displayed just across the E/S
window. Set net length and wire length on NET SONDE in the DATA
SET menu.
