This unit can show a position in degrees (36.14952°); degrees, minutes
and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds
and tenths of a second (36° 28' 40.9"). It can also show position in: UTM
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,
New Zealand, Swedish, Swiss, Taiwan and Military grids.
UTM's are marked on USGS topographic charts. This system divides
the Earth into 60 zones, each 6 degrees wide in longitude.
British, Irish, Finnish, German, New Zealand, Swedish, Swiss and
Taiwan grid systems are the national coordinate system used only in
their respective countries. In order to use these grid systems, you must
be in the respective country. This unit will pick the matching datum for
you when you select the grid. See the entry on Map Datum Selection for
more information.
The military grid reference system (MGRS) uses two grid lettering
schemes, which are referred to as standard and alternate MGRS on
this unit. Your position and datum in use determines which one to use.
If you use standard, and your position is off significantly, then try the
alternate.
NOTE: When the position format is changed, it affects the way all posi-
tions are shown on all screens. This includes waypoints.
