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
