    Description

    Cassens & Plath Polaris is a precision sextant designed for reliable astronomical navigation at sea. The instrument is manufactured in Bremerhaven, Germany, by Cassens & Plath, a manufacturer with a long tradition in marine navigation instruments. The Polaris model is designed for sailors and navigators who want high precision in a robust and professional instrument.

    The sextant is BSH type-approved by the German maritime authorities, documenting the instrument’s accuracy and quality in maritime use. This certification makes the model suitable both for teaching navigation and for practical use at sea.

    Polaris comes with a 4×40 telescope for clear observation of the sun, moon and navigation stars. The optical design provides stable and clear readings even in demanding conditions at sea, which is crucial for practical celestial navigation.

    The sextant is equipped with a clear-view mirror and a special lens for star observation. This solution makes it easier to observe navigation stars in low light and improves the accuracy of night navigation.

    The precision engraved scale and micrometer reading provide highly accurate measurements of the height of celestial bodies above the horizon. Together with nautical almanacs and sight reduction tables, navigators can calculate their position without the use of electronic navigation systems.

    Cassens & Plath Polaris is delivered in a quality case and can be delivered with personalized engraving. The result is a classic maritime instrument that combines precision, robust construction and traditional craftsmanship.
