I hope Charles and everybody else noticed that my comment was tongue in
cheek. In reality, I just didn't feel like getting deeper into the topic
because I didn't think that Lisa had asked about this particular aspect of
geomagnetic variation.

But then Fred Hebard replied to Charles

And here I beg to disagree. Most "GPS-only" users probably don't know how
to use their GPS to sail from point x to point y. A lecture on how to do
so should be forced on them by law. Have you ever wondered why GPS users
have a tendency to go around in circles? Every device that homes you in on
a target will do this in a side current. Those following correct piloting
procedures will not only be safer but also faster.

(I did it again. I know this is not how Fred meant it.)
