    Recertification of a sextant : Re: anyone familiar with a Luna Sextant?
    From: Greg B
    Date: 2013 Dec 26, 19:53 -0500

    Hi All,
          Does anyone know of a service that would check the certification
    of a sextant and supply me with a new calibration card? How much would
    this cost? Is it silly to do this on a instrument from 1982? The cert that
    came with it originally said: "no errors for practical navigation" but down in
    the lower right corner it said "RES: 0.02" which I would take to be a
    resolution of 0.02 of a degree i.e.; a little over a minuet of arc (0.016666)
    But I have seen certs on sextants showing errors in arc seconds. In practical
    terms how important is this?
    Thanks,
           ~Greg
