GPS derived positions are based on a worldwide reference (datum)
known as WGS 1984. Many charts are based on datums other than
WGS 1984. This results in an offset between a Lat/Lon plotted on the
chart and the same Lat/Lon plotted on the Tracker500/500i. To match
the Tracker500/500i with your chart you must enter the datum shown
on the chart. Alternatively, if your datum is not included in the list of
datums, you can enter an offset value to ensure the displayed lat/lon
values match the chart. Once you have entered a datum or offset
values for your chart, all latitudes and longitudes, including waypoints,
will match the chart.
USE
This option allows you to set the Tracker500/500i to
use either a datum or a position offset. The currently
selected datum and position offset values are
displayed in the bottom half of the screen. The
selected correction method has a box drawn round it.
