This screen shows that day's Tide Height graph for the area where the Tidal symbol was located.
Using [ZOOM IN] and [ZOOM OUT] it is possible to display future or past tides. If you wish to
quickly display the tide for a specific date, press [ENTER] and enter the required date.To simplify
reading the graph, the chart plotter displays a moveable Vertical and Horizontal slider which
can be moved using the cursor key. Using the up/down cursor key, move the horizontal slider
to correspond with the draft of your boat. Using the Vertical slider you can then read the times
at which the graph dips below the horizontal line i.e. the times when you will be in danger of
grounding.
NOTE
Tide graph is an approximation of the tide and they should be used in conjunction with
traditional tide tables and navigational methods. The Tide height value represents the variation
relative to the "Mean Lower Water" value.
