Depth and Height marker lines
The purpose of these marker lines is to provide an easy way to
monitor the depth of the gear. The Height sensor measures the
distance from the seabed and up to the sensor, while the Depth
sensor measures the distance from the sea surface and down to
the sensor.

Identify which of the sensors that are the Depth and/or
Height sensors.

to save the settings and exit to the graphic
display presentation.
The Depth and Height marker lines are presented on the
Graphic

colour as in the
Numeric

depth range on the right side of the display, or the readout in the
Numeric
display.
Spread marker line
The purpose of this marker line is to provide an easy way to
monitor the distance between the trawl doors.
1
Identify which of the sensors that is the Spread sensor.
2
Set the marker line to ON.
3
Enter the preferred settings for
Marker line thickness
and
Marker line delay
.

to save the settings and return the the graphic
presentation.
The Spread marker line is presented on the
Graphic
display
with a continuous line. The colour of the line is the same as the
background colour in the numeric presentation. To read the
distance between the trawl doors, consult the depth range on the
right side of the display, or the readout in the
Numeric
display.
If the trawl door distance is reduced or increased, this will be
easily detected as the marker line moves up or down. Note that
you do not monitor the depth of the trawl doors even though
you use the depth scale, the scale is used as a range scale.
