This function allows displaying, within the space of twenty-
four hours with respect to the selected date, the tide level and
tidal current speed and direction at a survey station in the
vicinity.
Unlike the estimated data shown in the Info window, this
forecast is much more accurate, being supplied directly by tidal
surveying stations.
Press GOTO, select NEAR by the CURSOR key, choose the Tides
or Currents service, then press ENTER to confirm. The GEONAV
will allow selecting one of the three nearest Tides and Cur-
rents stations. Use the CURSOR key to choose the station de-
sired and to confirm.
A window will show the information reported below.
