Current Information screen.
The Tidal Current Information screen displays daily tidal current data
for this station on this date at the present time. 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). The velocity
scale at the top left side of the graph changes dynamically based upon
the maximum velocity of the current for that day.
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:
1. Use → and ← to highlight month, day or year, then press
ENT.
2. Use ↑ and ↓ to select the desired month, day or year, then press
ENT.
To clear the information screen, press
EXIT.
Tide Information
Navionics charts contain Tidal Information,
represented at large zoom ranges by a box icon with
the letter "T." The icon stands for a Tidal Station
location. An example is displayed at right.
When you zoom in to a sufficiently small zoom range (1/2 nautical
mile), the icon itself becomes an animated gauge showing a rising or
falling tidal height for the selected station at the present time. At larger
zoom ranges, you can select the boxed "T" icon and it becomes an ani-
mated gauge with a pop-up name box.
To view tide information:
1. Select a Tide Station icon, then use the arrow keys to move the cur-
sor over an icon. When it is selected, a pop-up name box appears.
2. Press
FIND|FIND to display the Tide Information screen.
