The setup page leads to
may important screens that affect navigation. The most important screens are described
below.
GPS Made Easy explains map datum and how to select the right datum. Many maps have more than one coordinate grid, so it may be a matter of choice which one you use, but some maps have only one grid, so it is important to know how to use it. GPS Made Easy explains all the major grids and some of the minor ones. It provides in depth examples on how to use UTM and Latitude/Longitude. |
