Location Sub Tab

Refer to the “Appendix” of this guide for more information about

location formats and map datums. Also visit the National Imagery

and Mapping Agency at

http://www.nima.mil

for more information

on grids and datums.

Location Format Sub Tab

Changing the Location Format coordinates the system in which

a given location reading is shown. The default format is latitude

and longitude in degrees, minutes, and thousandths of a minute

(hddd°mm.mmm).

Map Datum Sub Tab

Datums are used to describe geographic locations for surveying,

mapping, and navigation and are not actual maps built in the unit.

The default setting is WGS 84. The unit automatically chooses the

best datum based on your chosen position format.

WARNING: Selecting the wrong map datum can result in

substantial location errors. You should only change the position

format if you are using a map or chart that specifies a different

position format or map datum or want to use a format you are

familiar with. When in doubt, use the default WGS 84 datum for

best overall performance.
