Tide or current forecast at the nearest survey station
NOTE: This function is available only with the NAVIONICS cartridges containing
Tides and Currents data.
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 Tide Info
window, this forecast is much more accurate, being supplied
directly by tidal surveying stations.
Press GOTO, select NEAREST 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 Currents stations. Use the CURSOR key to choose the sta-
tion desired and press ENTER to confirm.
