Loran TDs
If you have lists of fishing spots and other waypoints recorded
as loran time differences (TDs), the unit automatically converts
GPS coordinates to loran TDs. This feature is called Phantom
Loran™. You can display your position as TDs or enter way-
points as TDs. The accuracy to be expected from this conver-
sion is generally better than 500 to 1500 feet. You can also
interface your existing loran receiver to the unit, and then dis-
play and navigate with real-time loran TDs. These features
greatly ease the transition from using loran to using GPS. For
further details on using loran TDs, see ”Using loran” starting
on page 67.
TideTrack™
TideTrack displays a 24-hour tide graph for any of over 3,000
NOAA tide stations covering the entire U.S. coast, including
Alaska and Hawaii, as well as much of the eastern and western
Canadian coastline. Tides can be shown for today or any other
day you choose. For more information on using TideTrack, see
”Understanding TideTrack™” starting on page 139.
