    Ebbco sextant
    From: Mal Misuraca
    Date: 1999 Jan 23, 11:27 AM

      The Ebbco in my opinion is not a good sextant, either for beginner or more
    advanced navigation.  It tries to have a foot in both camps, but not
    successfully.  It is too plastic for the stability you would seek from a metal
    sextant, such as an AriesIII series, and it contains pretensions to optics and
    a drum micrometer that are likewise not of good quality.  You pay more for
    these pretentions, but they won't satisfy you for long.
    
    A much better plan, if you are a beginning navigator, is to buy the Davis Mark
    3 and use it until it no longer challenges you.  (This may not happen for a
    very long time; I still drag mine out every once in awhile and surprise myself
    how accurate it is.)  By then, you will know how far up the chain you wish to
    go for a better sextant.  In the meantime, keep your eye on the "used cruising
    gear" ads in sailing magazines.  The sailor who has become disillusioned about
    cruising across the seas will often advertise a new and very fine sextant for
    disillusionment prices.  That's the time to buy a better sextant, and not
    until then.
    
    I have taught for many years using the Davis Mark 3 for my students, and I can
    say with absolute confidence that it would if necessary take you safely around
    the world with considerable accuracy (say, 2 parts in 1000 n.m).  It lacks
    optics (hence, won't gather light from stars or planets very well), a
    micrometer drum (hence, must rely on a vernier scale---as did generations of
    R.N. navigators), and it's plastic (hence, needs to be protected from heat and
    being sat on).  But, pound for pound (or is it Euro for Euro, now?), dollar
    for dollar, it's a great buy---about $40 U.S.
    
    Good luck.
