Davis Mark 3 Sextant

Description

This sextant will enable the beginner to learn and practice the rudiments of celestial navigation at the lowest possible cost. It is made of heavy gauge plastic with an adjustable half mirror (which is equivalent to a traditional half silvered mirror). Although it is without magnification or illumination, it still works just fine. The vernier scale is a little harder to read closely than the micrometer scale on other sextants. It can also serve reasonably well as a back-up emergency sextant. An optional carrying case is available. SW 3 lbs. (List price $60)
