History

Which limitation influenced widespread sextant adoption despite their increased navigational precision?

A)Mirrors required complex high-reflectivity coatings
B)Brass construction was highly temperature-sensitive
C)Atmospheric refraction introduced significant error
D)Skilled observation reduces random measurement deviations

💡 Explanation

During open-ocean navigation determining latitude via sextant sightings requires skilled observation because random errors from a moving ship, weather, and limitations in human visual perception are common. Therefore, highly skilled practical user training was critical in obtaining accurate measurements, rather than superior design material issues, both of which have fewer practical observational impacts.
