Like Bruce, I have a Starrett level, actually two of the 98-8's - these are
8" in length, and I forget what one grad means in leveling per foot, or in
angular displacement, but I used them to set horizontal a dark glass plate,
for noon sights, and was quite happy with the results, although at the time I
was much more interested in basic concepts and procedures, than
minute-fractional accuracy.
Starrett does advertise levels accurate to 10 angular seconds, but they are
15 inches long, and very pricey.
