    Re: Aircraft Sextants

    Andr�s:
    
    I first found a discussion of using the Mark V sextant in "Self-
    Contained Celestial Navigation with H.O. 208, John S. Letcher,
    International Marine, 1977, ISBN 0-87742-082-3."
    
    I had access to a Mark V at the time and gave it a try. The bubble was
    VERY hard to hold in the circle while taking a sight, it jiggled all
    over. It made the sights using the bubble unreliable. It needed
    extensive modifications to make it handy for small boat use, Letcher
    says he paid $18.00 for his (1977). In 1978 you could get a Navy Mark V
    sextant surplus for $50.00. BUT, at the price now being asked for them
    I would by a Marine sextant.
