4.20 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:
