Well I just spent the day at a uk millitary training village and got some really nice gps data using this unit.
There is LOADS more than this, but this was what I recorded when I unpacked my laptop.
The rest of the data will take a fair while to wrestle with, ive got some walking page routes there which have varing satellite lock levels I want to compare. Me and google maps are going to have to get a bit more intimate to find a easy way to represent that data!
Anyhow, the units work a charm!
