What sextant are you using and is it properly adjusted?  I regularly get
within 1 nm in my fixes at sea.

	For reasons unknown, during the last few years I became interested
in celestial navigation, strange as that might be, for I'm not a
boating/sailing type.

	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.
