So, when I decide to circumnavigate I'll need several compasses?

I have to wonder at the fact of all the circumnavigation stories
I've read that not a single, solitary author even made mention
of compass dip?

I believe that the better compasses (all real compasses?) are built for either
the Northern or Southern Hemisphere, or have an adjustment.

Since the north magnetic pole is not resting upon the surface of the Earth
compasses made for Northern Hemisphere use are usually weighted on the
card on the southern side to keep the card more level as the north side of
the card seeks out the north pole buried well inside the Earth.

Are the compasses you Australian and New Zealand ******s use weighted
any differently? What if you were going to sail to Canada or something.
Would your southern compass work in the Northern hemisphere? Also
does you compass really seek the North magnetic pole or is it made
backwards to seek the south magnetic pole.

Enquiring minds want to know . . .

And either a boat or a plane.
