Target Aquisition Help

With the Towed Array, simplest way is to wait. Once the towed array has stabilised (that's why both move), then one will still be in the same bearing that it was before the turn, whilst the other will be at a different bearing.

For example -

Sub heading 0, 2 contacts at 90 and 270 with the one at 90 the real one. Turning to 45, after sub and towed array have both stopped moving, there will still be one at 90, however the other one will now be at 0.

Hope this helps.

As for the periscope, I'm not sure.

The best procedure for the periscope is to photograph the contact (do not mark it yet), go into the stadimeter station to determine range and course and only then mark the contact.
At that point the information will be relayed to the tma station, with a bearing line whose length is equal to the range you've just determined.
If you mark the contact without using the stadimeter then all you'll get is a generic bearing line without any range information.
If you want to generate a secondo line of bearing after 2-3 minutes, rephotograph the same contact the go into the stadimeter etc...
If you want to generate a line of bearing for a second contact, put the new contact in the periscope, photograph it, and redo the same procedure as I have detailed above.
Remeber to mark the contact only after you've determined range and course.
