Hi Wayne,
I agree that if you are careful with all listed "IF's", a compass
is a very good tool. But my experience with the sun's shadow and
a prediction from Heavens-Above (or a good pass prediction program)
showed me that I am not very good with at least one of your listed
IFs. I only offer it as an alternative to those who are equally
unsuccessful with that fine instrument.
73s,
