$350 · Davis Mark 15 Sextant Navigation Tool

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.   The Davis Instruments Mark 15 plastic 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 hard case is scuffed. The sextant has rarely been used and has never been exposed to salt water boating. https://www.westmarine.com/davis-instruments-mark-15-sextant-107722.html youtube https://youtu.be/MbZM-UBlw_o manual: https://cdn.shopify.com/s/files/1/0515/5992/3873/files/00026.710_WEB-H.pdf?v=1695495287
