Cassens & Plath Polaris is a precision sextant designed for reliable astronomical navigation at sea.<\/strong> 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. <\/p>\n

The sextant is BSH type-approved by the German maritime authorities<\/strong>, 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. <\/p>\n

Polaris comes with a 4\u00d740 telescope for clear observation of the sun, moon and navigation stars.<\/strong> The optical design provides stable and clear readings even in demanding conditions at sea, which is crucial for practical celestial navigation.<\/p>\n

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

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

Cassens & Plath Polaris is delivered in a quality case and can be delivered with personalized engraving.<\/strong> The result is a classic maritime instrument that combines precision, robust construction and traditional craftsmanship.<\/p>\n","protected":false},"excerpt":{"rendered":"
