The PROFESSIONAL is a top of the line brass frame sextant and perfect for celestial navigation at sea. PROFESSIONAL Sextant is certified by the Federal Maritime and Hydrographic Agency (BSH). The sextant features a full-view mirror. Supplied in a lightweight plastic case. Colour: black. As with all our models, the radius of the bow complies with international standards and meets accuracy tolerances.
Sextant frame and engineering design
This sextant requires sophisitcated machining to build. The frame is made from a brass plate that weighs 5.5 kg. Once the milling work is complete, the frame weighs approx. 0.6 kg. After milling, the frame is heated, straightened, sanded and engraved. The individual components are then fitted. The sextant consists of over 100 individual parts, most of which are manufactured in-house. All components are fitted and adjusted by hand. Each sextant is tested after production and a quality certificate is issued.
Full view mirror
The sextant features a full-view mirror. The central vertical part is half-silvered and therefore semi-transparent,
which means that you see the horizon and the star in the same picture at the same time. This has the advantage that the star/sun can easily be kept in the field of view in turbulent seas. This simplifies observation.
The semi-transparent mirror can reduce the brightness of the horizon image somewhat, which can make twilight observations more difficult.
