Thanks Red,
I actually have some proper corrector magnets but am afraid of using the
damn things for fear of bungling the job and ending up at the north pole
because of compass error.
The Dirigo does come in a presentation box sextant format, however, I assure
you that these compasses are indeed intended for professional work. You can
buy the basic gimballed compass (I have a 4" alnico model) and then make
your choice of housing units. From what I understand, the compasses are
popular with fishing vessels. You can purchase a binnacle for these,
complete with quandrantal spheres.
I guess what I am saying is the Dirigo Compasses are not toys or desk
ornaments!
