I regularly get within 1 nm in my fixes at sea. Jeremy In a message dated 9/18/2010 12:46:58 P.M.

In any case, getting "good" with a marine sextant requires practice with the thing, an activity that living inland makes difficult. A while back, looking though a Celestaire catalog, I came on the Davis Artificial Horizon, and purchased one. They also offer a Practice Bubble Horizon that mounts on the sextant. I have yet to obtain success with the latter, though he former works, assuming that one reads the brief instruction sheet that comes with it. Working against a Known Position (GPS coordinates), my calculated fix (estimated position) often falls well within 5 NM of KP. Granted, I'm not on a small boat, bouncing all over the place, however granting that, one can get about as much practice as they can stand with the Davis Artificial Horizon. As to time keepers, a while back I purchased a Casio G-Shock Atomic Watch, via Amazon. Paid about $50.00 for it. The thing is, and remains dead nuts on, as far as I can determine via checking with Official Time via computer, time data coming from The Naval Observatory. For the sake of clarity, aside from being, in a small way, a customer, I have no connection with either Celestaire or Casio. ---------------------------------------------------------------- NavList message boards and member settings: www.fer3.com/NavList Members may optionally receive posts by email.
