Observing Net Behavior
With net sonde connection you can observe net behavior after
the throwing of the net, on the echo sounder combination mode.
Accurate depiction of net sonde position depends on proper set-
ting of the distances between net sonde transmitters. You can set
those distances on NET SONDE XMTR in the DATA SET menu.
This function requires speed and heading inputs.
1. Press the SHOOT key just upon throwing the net into the
water.
Then, the net shooting mark ( ) appears at the own ship
mark and also at the right edge of the echo sounder picture.
Afterwards, whenever a net sonde transmitter on the net is
thrown into water, a net sonde mark appears on own ship
mark and moves with ship movement. The depths of net
sonde transmitter units are digitally displayed at the lower
left of the screen after the receiving transducer is placed into
water. The net sonde marks appear also on the echo sounder
picture as below, where the length of vertical line shows the
depth of the net sonde transmitter unit.
2. To erase net sonde mark and associated data, press the
SHOOT key again.
