yes to moove the needles (in particular the little) you need torpedo in tube and to moove the long needle (wich indicates the north at beginning) you have to go to periscopes or uzo and settle the view to the wanted bearing. then the long needle will indicate same bearing too.
2 zoom levels for uzo : x6 and x10
(with ctrl+mouse wheel, you can go freely from x1 to x12)
