Description
Cassens & Plath Professional Full View Illuminated is a classic marine sextant designed for precise astronomical navigation at sea. The instrument is manufactured in Bremerhaven, Germany, by Cassens & Plath, a manufacturer with a long tradition in precision instruments for maritime navigation. The Professional series is known for its robust construction and high measurement accuracy, and is used by long-distance sailors, navigation schools and professional navigators alike.
The Sextant is BSH type-approved by the German maritime authorities, documenting the instrument’s precision and quality in maritime use. This certification makes the model suitable for both teaching navigation and practical use at sea, where accurate observations of celestial bodies are essential.
Professional Full View Illuminated is equipped with a full-view mirror that provides a clear and stable image during observation. This optical solution makes it easy to align the celestial body with the horizon and provides an intuitive observation for both solar and navigation star observations.
The sextant comes with a 4×40 telescope that provides clear observation during navigation. The precision engraved scale and micrometer reading enable the height of the sun, moon or stars to be measured with very high accuracy, which is crucial when calculating position through celestial navigation.
The integrated lighting makes it easier to read the scale during night navigation or in low light. This makes the instrument particularly useful when observing stars, where the navigator often works in dark conditions at sea.
Cassens & Plath Professional Full View Illuminated is delivered in a protective case and with documentation of the instrument’s quality and precision. The result is a robust and reliable navigation instrument that combines traditional maritime craftsmanship with modern precision optics.
