    >> The compass rose on a chart shows the True heading on the
    >> outer ring and the Magnetic heading on the inner ring.
    >> What is the function of the innermost (third) ring?  It
    >> does not correspond to markings on either the True or
    >> Magnetic rings and I am baffled as to what its' purpose is.
    >> Can anyone on the list provide an answer?  Thanks.
