the dut is a good ship, but it is not better than the terrapin in every way. terrapin has better armour. its one shield covers less than half the area of the durs 2 shields, and has twice the power going to it. it is harder to detect. it is harder to hit, and it can take more hits. the dur is said to deal in cargo, and the terrapin in data. if you want to grab something of the wrecked ship before you sell its locatition you grab a dur. if you want to not be found, or survive being found as you look for the very valuable ships that salvagers will pay a lot more for, then you take a pin. if you want to recover a black box, you can put it in the bathroom. that way it flies around and damages the bathroom instead of the life support if you get in a fight. they are different ships. they do different things. and they are not fully implemented.
