The bearing accuracy is not good enough to do this by hydrophone. Visual sighting by periscope or UZO line is required.

I'm at work now replying on my phone. It is hard to describe the method I have in mind. Will do later today.

Derstosstrup did make videos with wolfpack showing the procedure some months ago.
