If you have the right 3-armed protractor, they arms are transparent with a
0.5mm or so thick black line to take the best reading. :-) It is quite
easy to use for anchor bearings and much faster than plotting 3 LOP's using
traditional plotting tools.

Yes Jeremy, this is my understanding of the "Steiner Point" method proposed in Gary's PDF, except using lines on transparent medium in place of protractor arms.

If I am reading this correctly, this is how you use a 3-armed protractor on a chart. Move the protractor around until the 3 arms are all contacting the bearing objects and you have your position. Sadly with my limited internet, i can't download Gary's attachment at the moment.Jeremy
