    Re: ebay sextant
    From: Fred Hebard

    The Mate had a 6" radius, and only one telescope.  On the other hand, it was very compact.
    
    Before WWII, Husun sextants tended to have most of the errors nulled out.  
    After it started, when production ramped up considerably, errors approaching 
    a minute of arc were allowed and most Mates had large errors.
    
    The Mate was more than good enough to get you there, and was a mainstay of British shipping during WWII.
