The Davis Mark 3 Sextant<\/strong> is a simple and affordable sextant designed for training in astronomical navigation<\/strong>. The model is often used on courses, in teaching and by sailors who want to learn basic navigation with a sextant<\/strong>. <\/p>\n

A sextant<\/strong> is used to measure the angle between a celestial body – such as the sun or a star – and the horizon. Using nautical almanacs and tables, you can then calculate your position at sea without using GPS. Although modern navigation systems are highly reliable, the sextant is still a useful backup instrument on board. <\/p>\n

Davis Mark 3 is often referred to as a “lifeboat sextant<\/strong>” because it is simple, robust and affordable. It was developed as a training sextant, but the model has also been used by sailors on long ocean voyages. <\/p>\n

The sextant is full size<\/strong>, which means that it works in the same way as more advanced metal sextants. It is equipped with solar filters and a clear scale for reading angles, allowing the user to learn the techniques used in classic astro-navigation<\/strong>. <\/p>\n

The Mark 3 has no optical magnification<\/strong>, which means it has no telescope. Observations are therefore made directly without optics. This makes the sextant easy to use in teaching and provides a wide field of view, but makes it more difficult to observe faint celestial bodies such as stars. <\/p>\n

Davis Mark 3 is therefore particularly suitable for training, teaching and practicing astronomical navigation<\/strong>, and is often used in conjunction with textbooks and courses in sextant navigation.<\/p>\n

This is a practical and affordable sailing sextant<\/strong> for those who want to learn basic astronomical navigation or have a simple spare instrument on board.<\/p>\n

The navigation shop Kart.no AS<\/strong> carries sextants and accessories for astronomical navigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
