This screen shows that day's Tide Height graph for the area where the Tidal

symbol was located. Using [NEXTDAY] and [PREVDAY] it is possible to display future

or past tides. If you wish to quickly display the tide for a specific date, press

ETDATE] and enter the required date using the cursor key followed by [ENTER]

once the date is set. 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.
