2. A sundial compass is a combination of these two instruments, consisting of a portable sundial
which is attached over a compass via a hinge. There are some adjustable legs that need to be
used to level the instrument if not on level ground. The gnome is hinged and needs to be put
in the up position where it locks into place. There should be what looks like a protractor that
is to the right of the gnome that is on a hinge, and this needs to be flipped up as well. The
protractor is used to set the sundial to the correct latitude angle, while the compass is used to
find true north based on the area's magnetic north declination. Once your sundial compass has
been leveled, set to the correct latitude, and to true north, a shadow will be cast onto the
sundial's face by the gnome. For use in the southern hemisphere, the same procedure is
followed with the exception that true South must be found instead of true North.
