Current Information screen.
The Tidal Current Information screen displays current tidal data for
the station. The graph at the top of the screen is an approximate view
of the flood and ebb pattern for the day, from midnight (MN), to noon
(NN) to midnight (MN).
Slack water, the period of little or no current, is represented by the
Slack Water Line (SWL). The flood appears above the SWL and the ebb
appears below the SWL.
You can look up tidal current data for other dates by changing the
month, day and year selection boxes. To select another date:

ENT.
2. Use and to select the desired month, day or year, then press

Tide Information
Navionics charts contain Tidal Information, repre-
sented at large zoom ranges by a box icon with the
letter "T." The icon stands for a Tidal Station location.
The figure on the right is an example.
When you zoom in to a sufficiently small zoom range, the icon itself be-
comes an animated gauge showing a rising or falling tidal height for the
selected station at the present time. At larger zoom ranges, you can se-
lect the boxed "T" icon and it becomes an animated gauge with a pop-up
name box. An example is displayed in the following figure.
To view tide information
1. Select a Tide Station icon: use the arrow keys to move the cursor over
an icon. When it is selected, a pop-up name box appears.
2. After selecting the Tide Station icon, press
WPT to display the Tide
Information screen.
