Submersible Information Thread

I've just gotten "Kamacite Ore" from Flickering Dip with only 120 Surveillance. I believe the consensus before was you needed 135 minimum? This may change things.

Am I the only one that finds it very disturbing that even with 105 retrieval, that sub is STILL getting the message "Poor retrieval levels result in disappointing yield."
