Hi Phil,
As a result of this article I have tried the system out - the software works
well and the error ratio over half a hectare was 1.9m.
The Garmin Emap GPS used in the article has now been discontinued.
The recommended GPS is now the Garmin Etrex Vista which you can see on the
link below

Kindest regards,

Dear list,
Following our recent discussion on the accuracy of HHGPS, devotees of
these gadgets may be interested in an article in the May/June edition of
British Archaeology entitled GPS Mapping in which the authors recommend
the use of a piece of freeware available from the web into which Garmin
data can be downloaded to produce maps. The website from which the
software can be downloaded free is
