    Re: Ebbco sextant
    From: Dan Allen

    I have the inexpensive Davis and I have not been impressed.  Screws have 
    fallen out of the mirror holder, leaving it unusable.  Even before this, its 
    accuracy was quite poor.
    
    If you think you are going to seriously want to do celestial nav and have it 
    as a backup (or primary!) source of position for a major ocean passage, treat 
    yourself to the Astra IIIb for $450.  It is all metal and will delight you 
    far more than plastic will.  I did this and it helped me get over the hump of 
    just toying around with celestial to becoming really dedicated and serious 
    about learning how to use a sextant.
    
    Or look around for a good used sextant.  You can often find other metal 
    sextants in the $200-$500 range if you look for a few months, or try 
    www.ebay.com.
    
    Spending MORE than $500 for a sextant doesn't buy you much, but I think every 
    dollar spent up to around $500 is worth it.

    Actually, imho, the Davis (either model) makes a good learning instrument
    (especially teaches adjustment and the need to check prior to use) and when you
    move on to a metal instrument, makes an excellent backup
    
    cheers,
    John
