Graphic display, pelagic trawl
A complete view of the fishing operation with pelagic or semi-
pelagic trawling is provided by a depth sensor attached to the
headrope, a bottom sensor to the footrope and a catch sensor to
the cod end. The echogram shows the relative positions of the
trawl, fish and bottom using an optional echo sounder transducer.
Bottom sensor ñ shows no bottom contact graphically repre-
sented by the red, downward pointing arrows not being in con-
tact with the horizontal line. Upon bottom contact, the arrows
will touch the horizontal line and change colour from red to black.
Bottom sensor measurement range is adjusted as needed.

Numeric display
Sensor depth - is rounded to the nearest meter
for depths over 100 m, otherwise it is displayed
to one decimal place. Maximum depth is 290 or
580 meters.
Catch sensor ñ represents the quantity of fish presently in the cod end. A
yellow rectangle indicates that the sensor has not been activated (no fish
caught). When the rectangle becomes red, accompanied by a peeping tone,
the sensor has been activated. Bottom and catch alarms are chosen from
Setup, sensor alarm and calibration.
Sensor information - illustrated here
with data from three depth sensors. Bot-
tom sensors can also be used for pursing
close to the bottom.
Depth scale - can be decreased or in-
creased using the respective - or + but-
tons on the keypad.
Bar graph - displays a ìside viewî of the
netís depth.
Alarm limits - both the upper and lower
limits are displayed.
Bottom sensor ñ black arrows indicate bot-
tom contact. Should the footrope lose physi-
cal contact with the bottom, the black arrows
will separate from the horizontal line and
change colour to red.
Rise/sink rate - is displayed in the se-
lected units per minute. Values near 0 in-
dicate that the net has stopped sinking.

Timer ñ displays how many minutes have
elapsed since the footrope lost contact with
the bottom or how long a catch sensor has
been activated. This timer is reset in the nu-
merical display setup.
