[OSGeo Africa] Field mapping GPS suggestions please

[Gerhardus Geldenhuis]

Hi,
I am no expert but I can't imagine that a mobile phone will be equivalent
in accuracy to something like a Trimble. You most certainly pay for the
brand but you also pay of the more accurate internal clock that plays a
crucial part in the error margin. I have used a Garmin 60CSx with a lot of
success doing Geological mapping. If you add an external antenna that could
also help with accuracy.

Regards
