Mark 15 Sextant



This model has many great features including seven large sunshades, a 3 mm x 27 mm star scope, and easy-to-read micrometer drum vernier scale that reads to 2/10 of a minute. The Mark 15 has a 7″ (18 cm) frame radius graduated from 120 degrees to -5 degrees and comes with a traditional half-silvered mirror.


The Davis Mk 15 sextant is proven at the equator and the north pole. This sextant is proof that you can navigate without GPS. It features large, easily adjusted mirrors using instrument-quality glass and a special baked on salt-spray resistant backing. Both mirrors have protective housings and the horizon mirror is half-silvered. No adjustment tools are required. The body is moulded using very tough weather-resistant plastic.

All Master Sextants feature the following professional specifications:

7 inch (178 mm) frame radius. Graduation 120° to -5°
Index mirror rectangular, 1.98 x 1.49 inches (50 x 38 mm).
Precision machined slow travel gear and worm mechanism.
Highly visible, easy-to-read micrometer drum and vernier allowing readings to 2/10 minute of arc.
Fully ribbed, three-circle sextant body for platform strength and stability.
Large, contoured handle designed for sure, steady grip and angled back for added control.
Seven large sunshades allow complete, independent adjustment of shading density for horizon and index mirrors.
3 x 27 mm star telescope with anti-reflective coated glass lenses, plus separate hooded sight tube for glare-free sun shots.
Neck lanyard frees hand and protects sextant.
Tough, fully padded, shock-resisting carrying case with compartments for extra batteries and mirror kits.
