Set and Read. The numbers and lines are not painted. They
are the same gray color as the rest of the sextant. So
you have to hold it just at the right angle in the sun light
to read it.

The venier is not a problem, but it is not as easy and as
quick as the micro drum. No modern sextant that I know of
is venier. It also slide around. The arm doesn't have
a lock or worm screw to hold the settings.

Like I said before, you need to check the index error
before every sight. Heat and cold causes the plastic to
expand and contract.

But, what do you expect for $14.00, which is what I paid
for mine.
