Well I've mailed them, asking for a permit. Although technically I wouldn't need one.
"Satellite Positioning Systems (SPS, GPS) used to determine the geographical coordinates in a site, for hydrographic and geodetic purposes (by the National Office of Hydrography and Geodesy)." Need a permit. And I'm certainly not geodating with my cyclo gps :p
But I certainly want to use my gps, because it's a mtb-adventure. And not just a single eartcache pick up I'll be doing... (wich I know, can be done with a smartphone).
But the discussion doesn't really help me further. Few recent posts and none that actually tried to take a gps, so...
