When you zoom in to a sufficiently small zoom range (1/2 nautical
mile), the icon itself becomes an animated arrow showing tidal current
velocity and direction for the selected tidal station at the present time.
At larger zoom ranges, you can select the boxed "
C " icon and it becomes
an animated arrow with a pop-up name box (the name box disappears
after a few seconds). Examples are displayed in the following figures.
To view Tidal Current information:
1. Use the arrow keys to move the cursor over a Tidal Current Station
icon. When selected, a pop-up name box appears.
2. Press FIND | FIND to display the Tidal Current Information screen.
Left, Navionics chart showing Tidal Current Station icon selected by
cursor. Right, the icon animates automatically without selecting it at
the 1/2 mile zoom range. The tidal current is flowing toward the
northwest at a velocity of 0.8 mph.
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.
