Davis Mark 15 Master Sextant with Star Scope

The Davis Mark 15 Sextant includes seven large sunshades, a 3mm x 27mm star scope, and an easy-to-read micrometer drum vernier scale that reads down to 2/10 of a minute, giving a genuine step up in precision over an entry-level sextant.

A 7-inch (18cm) frame radius, graduated from 120 degrees to -5 degrees, gives real range for celestial navigation, paired with a traditional half-silvered mirror that's stood the test of time on sextants of this style.

It comes with an instruction booklet, making it a solid choice for a sailor who wants real accuracy for actual celestial navigation without stepping up to the top-of-the-line Mark 25. Explore more marine networking.
