2.20 Observing Net Behavior
With net sonde connection you can observe net behavior after the throwing of
the net. Accurate depiction of net sonde position depends on proper setting of
the distances between net sonde transmitters. You can set those distances on
the OTHERS - INITIAL SETTING - NET SONDE SETTNG menu.
This function requires speed and heading data.
1. Press the [SHOOT] key just upon throwing the net into the water. The
following actions occur:
• Net shoot mark (
) appears at own ship position.
• Net shoot data appears.
• Net sonde mark is inscribed.
• Net depth data is displayed.
• Water depth data and water temperature data erased from own ship’s
track.
• In an ES combination mode, tide data and net depth replace the water
temperature graph.
• In an ES combination mode, the picture advance method changes to
“speed sync.”
• In an ES combination mode, the picture advance width appears on the ES
display.
2. To erase the net sonde mark and associated data, press the [SHOOT] key
