I'd suggest one of the recreational handheld Garmin units. If you don't need any mapping on it then a basic Geko or eTrex Yellow would be perfectly adequate. You might though think about the following, especially considering the geography angle. If you were to get one of the map displaying eTrex units or a series 60 device then you could collect GPS tracks, upload them to OpenStreetMap, edit the tracks into the road/path network and then upload the map to the Garmin unit. In that way students would be creating their own map from the GPS for the GPS and successive students would (and the general populace) would benefit from the efforts of those going before them. http://www.openstreetmap.org for more (and you can find user reviews of GPS devices on the project wiki). These handheld units will generally achieve an accuracy of +/- 10m in open conditions with a good view of the satellites. Under tree cover or in urban canyons they all suffer unless you go for one of the newer "H" range which use a more sensitive GPS chipset and fair better but these are a bit more expensive. Hope this helps. Cheers Andy Robinson (blackadder) _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking
