If the active GRI Chain, secondary stations, or offsets
have been changed since the waypoint was created,
the waypoint references the active GRI-chain and
secondary stations and adjusts the TD coordinates
accordingly. Remember that the eTrex is not relying
on the LORAN signal for navigation and actually
converts the TD coordinate to a useful latitude and
longitude coordinate before storing the waypoint to
memory or using it for navigation. Because of this,
the unit can navigate to a TD coordinate anywhere in
the world.
You must know your GRI chain number and
secondary stations to create a LORAN TD position.

Format Handbook, available on the Garmin Web site,
