I can currently see an Kubaz NPC on the same space as my X10 Patrol craft (sensors 3, owned by myself). When I get off the X10, I can no longer see it. I am holding a multiple sensor pack in one hand. I was under the impression, from reading the rules, that this would allow me to see the Kubaz on the ground. Why is it that I can still not see the NPC? What am I doing wrong?

Interesting...

I know the Kubaz's race bonus gives them 2 stealth, if you're perception skill is equal
to or less than that, you can't see him. The rules pages for the multiple sensor pack
says that it doesn't boost your perception, it only allows you to do a more detailed
focus scan of people you can already see. So if you can't see the Kubaz, you can't scan it.

I thought your ship's sensors over-ride your own perception if you were holding the scanner and the ship was at the same spot.

So I'm wrong?

Yes, you can only share sensors with a ship if there's a pilot in the ship.
So if it's your ship and you get out, you can't share sensors.
