Salut:
Drone sneaking: Without CoverOps autosoft drone is unable to sneak, so no, doberman or Dalmatian would not sneak. Ive used the drone just because we are following in their tracks, so the path should be clear, and because drone is some 50-100 meters ahead, so if anything goes wrong, we will have time to react for the situation before it reaches us, even Sam would be able to hide somewhere etc. Otherwise Sam would be the forst one who runs into the danger
As for sneaking...since Sam doesnt have the Astral sight and have no idea how it looks like in there, also...taken into consideration there wery little lifeforms down there, IMO it wont be any help.
I dont want to steal Your spotlight, Kour, well IMO its better to risk a piece of metal and electronics which costs 2200Y, than human life in this situation. Considering that automatic machine wont necesarry mean that there is group of runners behind it, and it moves much faster, even in tunnels, this mechanized survey may be done in some intervals...Id say 250 meters as I wrote before. Then we get to the spot, then another 250 meters. When we find last RFID marker, Ill eave this completely up to you, because further there would be alien space...
