I know nothing about UA scannersBut weapons in other ships can be detected just with the basic scan (lock onto a target ahead of you). I don't play in Open, but as far as I know that's a passive scan and isn't detected by the craft being scanned.
We get a "Scan Detected" message when scanned with a Cargo (or Kill Warrant?) Scanner scans us. But it's a bit of an assumption that this UA scanner behaves the same as those we're used to.
Thanks for your reply, that's what I thought. I think we should keep thinking that it behaves like the scanner we have, otherwise what's the point of including a new behaviour similar to one we already know if it does something completely different from what we're used to?
Each new thing brings more questions than answers. :1
