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.
