Almost forgot. I made my own sliderule for this. Makmak94 included it in his Magui mods.

Forget the note about 'angle on relative motion'. It causes more confusion than it clears up. Just go as slow as possible, dead stop if you can. Or if you must have speed to keep depth, head slowly in a direction towards the initial hydrophone bearing. (but keep rudder amidship! Make sure you are not turning while you are waiting for the bearings)

And very important is to stay patient during the process. The longer the period between the bearings, the more reliable or precise the AOB will be.
