Hi Peter,
I have a fair collection of sextants and have tried different makes
and models in actual conditions. If you are looking for a model that
you can use on a small boat I would highly reccomend the russian navy
SNO-T. These sextants can be bought on e-bay for around $400.00 actual
cost. I say this because the selling price will probably be in the
$250. range and $100. shipping and from the russian sites they do not
accept paypal and you have $45 wire transfer fee. I would stay away
from some of the sites in India that are selling sextants from
demolished ships. The SNO-T is basicly a copy of the plath. As far as
artificial horizon's you do not need one that attaches to the sextant.
Davis instruments makes one that you can put a reflective liquid in
and shield the sides from wind. You would bring the celestial body
down to coinsidence with the reflected image and devide the angle in
half. I have spent many afternoons taking sun shots with these. The
heavier sextants like the Tamaya and C-Plath are great sextants but
are hard to handle on a small pitching vessel.
