SIGHT REDUCTION TABLES FOR MARINE NAVIGATION Pub. No. 229 (HO-229) - Commercial Edition

This is the standard set of tables designed for marine navigation. Although there are 6 volumes in a set, only those pertaining to the latitudes anticipated need be obtained. Their tabular data, being purely mathematical results, never go out of date. The latitudes listed for the Volumes work for either northern or southern hemisphere.

Because of the high price and spotty availabliity of the Government editions,we have reprinted these as Commercial Editions from official Government electronic files. They are economical, and sized at 90% of the originals. They have soft instead of hard covers and their smaller size of 8.5 x 11 inches is easier to carry and store. SW 2.1 lbs
