Yeah spot on about the lines at the bottom. I forgot which clever person made that overlay.
As the cool people who made the sound trainer pointed out you can do all your firing from the sound room (which is great if conditions are terrible or there are eyes looking out for your periscope).
This method takes it a step futher and we can now calculate courses, bearings, ranges just from sound
One flaw of the sound tutorial method is that it is hard to line yourself up to the desired AOB without using the periscope. Now we can as we know the target course. We can still use the tables but as we can now extrapolate range we can manually configure the TDC if we want as well.
