Now how did I know this thread would appear
I never fire salvos at fast movers unless all four eels are the same type because the game automatically defaults every eel to that of the slowest one in the salvo mode.
I set each eels depth and speed prior then fire one at a time, quickly pressing Q after each launch and allowing a few seconds for the door/hatch to open.
Hope that makes more sense considering how it reads
