One caution on saving Events. For maximum accuracy, it’s best to be sitting

next to the desired location and let the readouts settle down for a few seconds
before pressing

If you are flying by a buoy at high speed,

the readouts will be displaying a position lagging behind the boat a short
distance. The faster you are moving, the greater the lag error will be.

Each time you store an event, the coordinates can be remembered as either

a loran, GPS, or DGPS position. Since there will be absolute position
differences when using the different systems, the

NAV 398

memorizes the

type of position data (L, G, or DG) recorded for each event and shows the
indicator on the screens when the Event is used for a destination waypoint.

The indicators L, G, or DG appear immediately after the WPT characters on
the screen. In this way, the operator can use the matching systems to return
to Event locations more accurately.

It’s a very good idea to write the Event numbers and location descriptions

onto your paper

log for future reference at the first opportunity.
