One of the most important things to keep in mind when using a GPS is the
number of satellites that you are able to track on. If you are in a place
that you only get two tracking, your readings will not be that accurate.
three is bare minimum to get a seasonably accurate fix. four or more should
put you right on the money when you take a fix. There is also the
possibility of difference's due to the type of unit and lots of other things
that affect GPS usage. Even the expensive ones that we use in the military
can be off if the conditions are not ideal for tracking in the satellites.
