    Re: Astro COmpass Manual on line?

    That was a great reference, and I 'm sorry I didn't see it first. However,
    the major use that I recall for the Astro Compass was by aircraft flying
    near the earth's poles where you can not get a reliable magnetic reading
    from a standard compass.
    
    When used for that purpose since it was North that you were trying to
    determine, the portion of the instructions that were most helpful were in
    the section that had to do with proving the set-up.
