But I myself made a tool that allows you to calculate course/aob with three bearings only if you are not moving. As I said, I have no idea if the germans or even the americans used this technique during the war. Just that it can be done with enough patience.

Ive worked out how the geometry works with this slide rule, and I'm very impressed with it. I particularly like the fact that it does not religh on the unreal parts of the hydrophone such as me hearing a target at 34km but the sonar operator only hearing at 20km (I dont want to detract from what raduz has done with his excelant tutorial, I just want to try out what was possible in 1939-45)
Presumably you get from this an AOB and therefore the heading of the target, but you still have to use skills in listening to the hydrophone to gauge the range to target and his speed (which would help you gage his range in relation to the 3 bearings.
Ive not tryed it out yet as I tried moving the hydrophone hunting tutorials into the program files, caused the game to crash and I have ended up having to reinstall the origonal version from my DVD. Its just finished reinstalling.
Thanks.
