Couldn't help but put in my $0.02 worth.

I have two metal sextants and a plastic one. A Friburger,
an Astra IIIB, and a Davis plastic (el cheapo) one.

The Davis plastic is by far harder to use and to read,
than the others. The key word is read. It is a venier
rather than a micro drum.

The index error has to be checked at every sight with
plastic sextants. They are subject to heat changes,
way more than the metal ones.

However,

in the hands of a skilled navigator a $25.00 plastic sextant
would be better than a $3,000 metal one in the hands of
a person who doesn't know what they are doing.

Moreover, I don't include myself in the "skilled navigator"
crowd. But, I am smart enough to know that sights and calculations
in my back yard are a lot different than on a pitching boat
out in the ocean. I would be just as dumb as the next land
lubber.


It is just like when I was in college taking math. Kids would
bring in $300 and $400 calculators thinking that would get
them an A, and the smartest kid in the physics class
(not me) had a $15 TI. This was back in the '79.

"Doc, when my finger heals, will I be able to take sextant
sights and find my position within 5 feet. "Don't see why
not." "That's funny, never could before.".
