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, 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. Move the cursor over to a Tide Station 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.
