Taking into consideration I have no antennas or arrays with a very narrow
beam width I used the "I think it's about that-a-way" method for finding
North.
For astronomy (Telescope set up) I rough set with the Isogonic lines and
fine tune it from there, but that is an entirely different topic and one
that does require precision.
