Mark 15 Master Sextant

A sextant is an excellent tool to have on board any size craft as a backup in case there is a failure of the navigational systems. Used to measure the angular distance between two visible objects, the most common sextant navigation points are an astronomical object and the horizon. Sextants have many uses, ranging from measuring the distance of a landmark to determining Greenwich Mean Time.

The Davis Instruments Mark 15 sextant navigation tool includes seven sunshades and a micrometer drum Vernier scale that reads to 2/10 of a minute. It has a 7-inch frame radius that is graduated from 120 to -5 degrees. This sextant navigation tool also comes with a traditional half-silvered mirror. This model comes with a durable hard case.

The Mark 15 is a traditional sextant that provides accurate readings of many object pairs. It is lightweight, and the swingarm is easy to move with a smooth action. It also comes with an instruction manual that is easy to follow. A sextant is a simple instrument that is easy to use once you try it a few times.
