CASSENS & PLATH Artificial navigation horizon for Sextant

The artificial navigation horizon is required to measure the celestial altitude with the sextant when there is no horizon visibility, for example at night, in ground fog, when travelling under land or for land navigation.

The artificial horizon can be used on all CASSENS & PLATH sextants that are equipped with illumination because it requires a power supply. These are the sextant models Horizon Ultra, Polaris, Bobby Schenk and Professional (with illumination).

The artificial horizon can be easily exchanged for the normal sextant telescope thanks to its clamping screw. No adjustment is necessary.

The device is used as a normal sextant telescope (3 x 25 mm) with a bubble level inserted into the optical path. A crosshair and the dragonfly bubble appear against a red illuminated background. A dimmer allows the brightness to be optimally adjusted to the external light conditions. An additional shade glass can be attached to the lens for solar observations.

The artificial horizon is suitable for navigation and is approved for commercial shipping under BSH/047/01/78.

For purely training purposes, the artificial training horizon (Article-No. 3716-113) is an inexpensive alternative. You will find this further down the page under "Similar products".
