Almost all maps use WGS 84. Old maps are usually NAD 27. Nearly everyone uses the WGS 84 datum with their GPS units.

Subject: [meteorite-list] Garmin etrex GPS question



Hello to the List,

I know some of you use the etrex GPS (Garmin).

I would like to know how to configure it for the
western USA (California, Arizona, Nevada).

Which geodesic system should I use to have correct gps
coordinates in the USA ?

Thanks in advance,

Pierre-Marie PELE
