Thanks UberTorpedo. (Since I made it) It is an AOB-finder tool. Though it's not exactly what the OP was looking for. He is looking for something that works like the bearing/course/aob side of the Attackdisk. (In the PaulWasserman link the "Etchasketch’s AoB finder wheel" is mentioned, which does that)

But please let that not inhibbit somebody to try it out. Given enough time it is very accurate.
