I started out navigating with a Davis plastic sextant in 1963(?) or there
abouts. I used it on trips to/from Hawaii, Baja, and up/down the coast. For a
small boat it kept an accuracy of 4 Nmi+/-. Used it up to 1984, when I left
it laying on a plastic cushion on the way to Santa Catalina Island one summer
day, it tried to turn into a ball. Then I bought a used Huson, I used it
until I got talked into exchanging it for a Freiberger.
IMO a top of the line sextant is required only if you are going try Lunars.
Otherwise, for *PRACTICAL* small boat navigation, most modern sextants will
work admirably.
Consider these errors:
Your eyesight
Boat motion
Your plotting error
Your method of sight reduction
Any time error
And, any errors in the charts
