    Works well in the US - Canadian border region, but since it's in my
    glove compartment I can't remember it's name.  About the size of a
    small matchbox, and has a drop down chrome plated mirror for sighting
    magnetic azimuths.  Suumo, maybe, possibly made in Switzerland instead
    of Finland; has the bar on a little gimbal under the needle.
