If it wasn't for skill-loss, you could go into a new territory with your 2nd-best gear, or even with trash from your bin, and gather intel until you are killed for free. Then you could put on your super-suit to go back for the plunder. Your tomb would even give you a corpse-run boost.

Though you can do it without it, thanks to the cartography table, it's even more convenient to use a second character to do this with. You don't need very high skills to scout a zone instead of using the main character. When you finally get back to base you can just enter all your discoveries and copy them down on the main.
