Warning

During my tour from Switzerland to Nordkapp, I carried a hand-held Eltrek Summit GPS device manufactured by Garmin with me. Unfortunately, I was under the misconception that latitude/longitude coordinates would be independent of the map datum to which the device was set, and I therefore left the device set to its usual Swiss CH-1903 map datum. The coordinates given in the various reports of the trip will therefore not correspond to coordinates obtained with a device set to the more universal WGS84 map datum.

If anyone can point me at a reasonably handy transformation tool, I'd be most grateful.
