Description
Cassens & Plath Horizon Ultra is a professional sextant designed for precise astronomical navigation at sea. The instrument is manufactured in Bremerhaven, Germany by Cassens & Plath, one of the world’s most recognized manufacturers of marine navigation instruments. Horizon Ultra represents the top level of the manufacturer’s sextant range and is used by long-distance sailors, expeditions, navigation schools and professional navigators who want maximum precision and robustness.
The sextant is BSH type-approved by the German maritime authorities, documenting the instrument’s precision and quality in maritime use. This certification is an important standard in professional navigation and makes the instrument suitable for both navigation training and practical use at sea.
The instrument is constructed with a solid precision frame and high quality optics. The sextant comes with a 4×40 telescope that provides clear observation of celestial bodies during navigation. The polarized solar filters make it possible to observe the sun safely and precisely, while the advanced optical system provides stable and clear readings even in demanding conditions at sea.
Horizon Ultra is equipped with Schüler double prism, an optical solution that provides very high measurement accuracy. Combined dip and index error correction makes the instrument easier to adjust and provides more reliable measurements during practical use. This is one of the reasons why the model is popular among sailors practicing classic celestial navigation on long voyages.
The precision engraved scale and micrometer reading allow you to measure the height of the sun, moon or stars with high accuracy. Together with nautical almanacs and sight reduction tables, navigators can calculate their position independently of electronic navigation systems.
The Cassens & Plath Horizon Ultra comes in a high-quality case and with a neck strap, and the instrument can also be delivered with personalized engraving. The result is a professional navigation instrument that combines classic maritime craftsmanship, modern optics and very high precision.
