How to set up marker lines
When you have chosen the Graphic display presentation, you
can choose to superimpose the information from the echo
sounder, and then add marker lines to see where your sensors
are located in relation to the bottom and fish echoes. Note that
the echo sounder data will only appear if you have mounted an
echo sounder transducer to the PI32.
The following parameters will affect the way the marker lines
are displayed:
•
Width - you can select how thick (in pixels) each marker line
shall be.
•
Delay - The echo sounder information is provided by the
transducer, and this transducer is located under the vessel.
The sensors are located on the gear, which may be positioned
several hundred meters behind the vessel. To adjust for this
delay, you can enter a value for
Marker line delay . You must
calculate this value (in minutes) based on the vessel’s speed,
the wire length and the depth of the gear.
Alternatively, you can use the built-in Trawl caluclator to
find the correct delay.
•
Colour - The colour of the marker line is automatically set to
the current Numeric display background colour for the same
sensor. To change that colour, you must access the Display
colour setup page from the Setup menu.
