    The Astra IIIB has somewhat revolutionized celestial navigation. Never before has such a high quality, accurate metal sextant been available at such a low price. Over 23,000 sextants of this model have been sold in the US alone in the past 26 years, far more than any other serious sextant. Its popularity has spread throughout the rest of the world as well, making it the the most recognized (and supported) sextant worldwide.

    Its low price, excellent optics and choice of horizon mirrors and other accessories makes it the perfect selection for beginners. Yet, we know several professional navigators who prefer the ASTRA IIIB merely because they can leave their expensive models at home without sacrificing noticeable accuracy.

    Features:

    • Ability to quickly and economically change the type of horizon mirror
    • Inexpensive replacement parts aids maintainability when students mishandle the sextant
