CASSENS & PLATH Professional Marine Sextant with Fine Wooden Case

Sextant by CPsailing with traditional half silvered horizon mirror

Sextant frame

Made of seawater resistant aluminum. The 153 mm radius of arc grants high accuracy and reliable comfortable readings of the star altitude. Because, as a matter of fact, the bigger the radius of arc, the higher the technically possible accuracy of the instrument.

Sextant mirror

Polished crystal glass, optical errors less 10". Seawater resistant silver coating covered by protective varnish. Scratch proof full view coating. The traditional half-silvered horizon mirror is made of glass even on the transparent side. This prevents optical errors and the accuracy will be increased. Full view and traditional mirror are held within a solid frame to protect them against impact and de-adjustment.

Shade glasses

Four index- and three horizon shade glasses, fully tinted and of different, optimally harmonized transmission. The combination meets international standards and secures best adaption to every possible condition of brightness.

Telescope

High quality 3.5x40 telescope of type Galileo. The 40 mm entrance pupil collects enough light for comfortable twilight or night observations. A field of view of 9° or 160 feet/1000 feet ensures safe finding and keeping of the star, even in rough waters.

Drum and Vernier

The vernier ensures comfortable readings of the star altitude with an accuracy better than 0.2'. The navigator does not have to rely on estimating the value.

Illumination

Arc and vernier are illuminated. The battery and the push button are integrated in the sextant handle.

Accessories

The sextant is stored within a wooden case. Rich accessories are enclosed: Mirror adjustment key, special sextant oil, a rag to clean the optical parts, brush, operations manual quality certificate.
