The HORIZON ULTRA with its polarized shade lenses and the double prism (Schüler) is a specialist for sun observations.

The double prism deflects the horizon viewing beam to the right and left of the sun's reflection on the water, thus preventing illumination-related measurement errors. In addition, any vertical inclination of the sextant can be detected immediately.

Furthermore, there are scales for a combined dip and index error adjustment on the drum screw. This index error adjustment on the sextant was developed by Bobby Schenk.

The polarized shade lenses can be continuously adjusted to the different light conditions in horizon and celestial direction.

With the full view mirror you won’t lose sight of the star even in rough seas and heeling of the yacht.

Please note: The 6 x 30mm telescope as well as the artificial horizon do not fit together with the sextant in the Rough Case. Here we recommend the wooden case, in which an additional holder is attached.
