GPS Setup - Coordinates

Coordinates refer to the grid system the hiker uses to identify position location in the backcountry.  Latitude and Longitude is an example of a coorinate system that can be used.  The GPS receivers offer a lot of flexibility and use many of the key formats found worldwide.

I have received a few emails about what coordinate system to use with a GPS?
Coordinate system refers to the geographic grid used on a map; Latitude and Longitude is a coordinate system.  The GPS receiver may call it position format.
My recommendation would be to consider:
1.    When traveling outside of the United States find out what system the visited country uses.  The GPS receiver has coordinate systems pre-loaded for many countries around the world.

a.    On a Garmin select “Setup” then select “Units” (below).

b.    Select the drop down menu under “Position Format” and rocker down to view the country options.
c.    If on a tour or with a guide ask which coordinate system they use.
