: Paul: Fair questions. My day job is in the forest industry in the southern
: parts of BC. Magnetic north is currently ~21.5 degrees off of true north.
: My Silva pocket compass allows for an adjustment to allow for declination.
: Thus the bearing I read off of the map I can translate immediately to a
: field sighting without needing any mental calculation.

: Although the BC coast should be slightly less declination it just seemed to
: be a logical assumption that deck mounted compasses with adjustments for
: declination would prove invaluable. Perhaps I am missing something in the
: use of nautical charts?

Their compass roses show magnetic north, so it's quite easy to navigate off magnetic bearings.

: I also have a GPS that I use in the field and might take with me for safety
: purposes but it would probably remind me too much of work.
