Scanning Equipment


Having being stung in a previous campaign, my players want to install some heavy duty scanning equipment in their ship to scan cargo, before it is loaded. This would ideally be similar to the starport customs scanners. I can find a handheld weapons scanner, but I can't seem to find any other equipment to do the job. Am I going to have to make something up, or have I just missed it?
Adjacent range, so within 1 km (still very long when parked/docked at a star port).

It’s expensive, but how large containers do you need to be able to scan?

1 ton sensor lets you scan 12x 4 dton containers per hour, or one every 5 minutes.

Slap on an arbitrary discount for vastly reduced range?
