A sundial compass is a combination of these two instruments, consisting of a portable sundial that is attached over a compass via a hinge. 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 on a hinge, and this needs to be flipped up. 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 true north, a shadow will be is 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.
