Creating Waypoints In The Loran Td Format - Garmin GPSMAP 235 Sounder Owner's Manual

Creating Waypoints in the LORAN TD Format

Waypoints can be created graphically, using the Mark Key, and by Text Entry (see
page 53). Waypoints can also be created using LORAN TDs. To create a waypoint
using the LORAN TD Position Format:
1. Verify that the correct GRI Chain and secondary stations are selected on the
'LORAN SETUP' page.
2. Following the instructions given in the Waypoint section of the manual, begin cre-
ating a new waypoint.
3. Highlight the position field and press ENTER.
4. Using the data entry technique described in the Waypoint section of the manual,
enter the TD coordinates. When finished, highlight 'DONE' and press ENTER.
You can now navigate using LORAN TD waypoints the same as you would using
GPS waypoints. Remember, the GPS converts the TD coordinate to a LAT/ LONG
coordinate for use by the GPS. To improve accuracy, update the location informa-
tion when you are at the site, since the waypoint gets converted.
