Navaids
The SporTrak Color now provides mariners with navaids added to their waypoint
database. These navaids can be used as any other waypoint and are easily accessed
through the Database function of your SporTrak Color receiver.
Tides and Currents
SporTrak Color users can now access tide information for ports that are stored in
their basemap. If a chart from one of the Magellan MapSend BlueNav products has
been uploaded, additional tide and current information can be displayed for ports/
stations that were included with the chart. (Please note that not all MapSend
BlueNav charts contain station information.)
The Tide Screens
The Tide screen displays the times for high and low tides, the water height and the
coefficients (French internal ports only) for a selected date and port. The dis-
played water heights are the height of the water at the lowest astronomical tide.
These values are provided as a rough guide and may vary with weather conditions.
Accessing the Tide Screen
From any screen, press the Menu key. Use the up or down
arrows to highlight “Tide” and press the Enter key. When a
MapSend BlueNav chart is uploaded and has been selected
as the detailed map (see Selecting a Base Map or a Detailed
Map) the menu option displayed will be “Tide/Current”.
Changing the Date
1) With the “On” field highlighted press the Enter key.
The “On” field will go into the edit mode.
2) Use the up and down arrows to change the data at the cursor position and
use the left and right arrows to move the cursor.
3) When you have the date desired, press the Enter key. A pop-up window will
be displayed indicating that the SporTrak Color is calculating the tides.
Changing the Port
1) With the “At” field highlighted press the Enter key.
2) If you have a MapSend BlueNav Chart loaded, you will be given the op-
tion of selecting internal ports or MapSend BlueNav ports. Use the up or
down arrows to highlight your selection and press the Enter key.
3) If you selected to use the internal ports, you will be asked to select a region
to search from. Use the up or down arrows to highlight the region and
press the Enter key.
